What is a Berg Timer Profile?
Data Sources

BT's "7" strength on April 1 and "12" strength on April 6 causes a resumption of terror activity with car bombing on 27 March in Yemen killing 10, 2 executions in Egypt, a truck bomb in Iraq killing 17 on March 29, 12 killed in Nigeria by Boco Haram on the 30th, and 24 killed in Pakistan on March 30.
Also related to BT's strength here in early April 2017 is the extreme weather activity in the Midwest causing tornadoes with several deaths.

Due to the evidence presented here, it can be concluded that the planets, when in certain predictable positions as represented by the Berg Timer, cause solar activity and its ionized particles to affect Earth's atmospheric nucleation causing cloudiness which increases atmospheric angular momentum which increases length of day and sea level.
Thus BT can forecast weather and most all things that weather affects,
which is just about everything.

And God said, "Let there be lights in the firmament of the heavens to separate the day from the night; and let them be for signs and for seasons and for days and years".  The Holy Bible, Genesis [1:14]

My aim is to say that the machinery of the heavens is not like a divine animal but like a clock and that in it almost all the variety of motions is from one very simple magnetic force acting on bodies, as in the clock all motions are from a very simple weight.
Johannes Kepler, late 16th Century, founder of three laws of planetary motion.

The relationships set forth here imply that certain dynamic forces exerted on the sun by the motions of the planets are the cause of the sunspot activity.
Paul D. Jose, Aerospace Research, USAF. The Astronomical Journal, Vol. 70. April 1965.

It is found empirically that solar activity is preceded by planetary conjunctions. A long-range prediction technique has been in use for 2.5 years, which predicts flares and proton events months in advance.
J.B. Blizard, Denver University. American Physical Society Bulletin #13, June 1968.

In summation, after more than 25 years of research in this field of solar system science, I can say without equivocation that there is very strong evidence that the planets, when in certain predictable arrangements, do cause changes to take place in those solar radiations that control our ionosphere.
John H. Nelson, RCA Communications. Cosmic Patterns. 1974.

The words above were spoken or published by religious teachings and respected science journals and authors.  They have been personified by the Berg Timer since 1980.  The Berg Timer Profiles, first developed July 2016, provide an objective and practical way to apply BT.  

This body of work represents the bringing together of the wisdom of the ancient astrologers and the accuracy of today's astronomer to demonstrate that all of the universe's physical and biological paths are inextricably linked to the planets.  From the ancient Aztec and Maya civilizations, the 13th Century's Ptolemy and Dante, and the Renaissance's Galileo, Kepler, and Brahe who overturned the old astrological order, to today's technologically accurate astronomers.  All share the common goals of truth and the value of scientific understanding.

They were all, at their roots, astrologers.  They all knew and understood that their environment was affected by the heavens.  And they were astronomers.  They knew that detail and strict rules of analysis and logic brought their theories home with facts.

Larry Berg, astronomer & astrologer, self funded and self taught in astrophysics, solar physics, meteorology, and the planetary sciences, has created one indicator capable of forecasting most all things related to the regularity and cycles of the sun, the planets, and the weather.  

This, his life's work, is now meeting its fruition.  Here, in his early 60's, with his new BT Profiles, he is demonstrating that the capability now exists to forecast not only planetary effects but also many environmentally sensitive aspects of our lives.  Ancient astrological wisdom has been coupled together with today's precise astronomical calculations to form one simple, yet all-encompassing forecasting tool,  
The Berg Timer™. 

The Berg Timer was discovered on November 19, 1980.  Its applications on this website are the result of over 40 years, and tens of thousands of hours of concentration, labor, sacrifice, data acquisition, analysis, frustration and discovery.  A special "thank you" to all the scientists, engineers, and researchers in all fields of study who make data available for research.

Hi, my name is Larry Berg.  Ever since I turned over my first rock as a child, I've been fascinated by Nature.  My passion has been the study of natural cycles, specifically, the relationship between planetary cycles, solar cycles, and the cycles of Earth's weather, biosphere, geology, and human behavior.

It's to everyone's benefit to have a good understanding of the future.  Whether it's weather, sales, politics, science, the markets, or health services . . . everyone is dependent upon, and subject to, future circumstances.  Knowing more about natural cycles and being able to predict the future enables one to decrease the probability of allowing things to happen by chance and, thus, have more control over one's life and business.  

I developed a simple indicator which can forecast many things, very reliably.  Farmers and traders now know when the next drought will occur, and when it'll be rainy and cool.  Emergency services now know when accidents are most likely to happen.   Power companies know when to expect geomagnetic storms.  Business owners can forecast sales strength.  Stock market investors know when to buy and sell.  Now we all know when to schedule outdoor activities and travel for the best weather.  Anything you want to know that's related to weather, which is just about everything, can be forecasted by the Berg Timer.  

Since BT is based on planetary positions, and planetary positions can be projected with precise accuracy, BT can forecast infinitely into the future with no loss in reliability.

BT's applications are so broad that any institution, business, or individual can benefit by applying it to their particular activity.

Welcome.  Join me as I turn over some more rocks.

What Is the Berg Timer?
The history and development of the Berg Timer can be read at http://www.justgoodtiming.com/id48.htm.  Essentially it began with an interest and understanding of astrology way back in my 20's.  I found it accurate and reliable in a couple ways.  My understanding of astrology was so thorough that I could often guess someone's sign just by observation.  So I knew that there must be a larger application for it in the world.  That led me along the long road of discovery.  There's really nothing like the feeling of discovering something no one has ever known before, especially since it might be a new law of physics!
How the planets' positions can affect solar activity is not known.  I believe it is the planets' effect on the interplanetary magnetic field.  We will need space buoys throughout the solar system in order to measure it.  That day will come.

The Berg Timer is simply a summation index of the number of times two planets are longitudinally equidistant from a third, with respect to the sun.  So when the heliocentric longitudes of two planets are the same distance to a third planet, a value of "1" exists of the Berg Timer.  Typically, these are called midpoints of the planets --- one planet is in the middle and two planets are on either side of the middle.  The other time a BT value exists is when there is a planetary conjunction, when two planets are in the same longitudinal position.  At this time those two planets are equidistant to all the other planets.  So there automatically is 7 points for the Berg Timer.  When you add up all these BT points you create a series of values for whatever time period you want, together forming an oscillating cycle.  I typically use daily, monthly, and yearly BT for my correlation studies.  

In my early days in the late 70's, with no computers, I drew all the planetary lines by hand.  That took me about two days to do one year of the BT values.  Now with the computer I can calculate BT for any year in about seven seconds.  So I now have a library of BT from the late 1500's to 2300. 

What Is a Berg Timer Profile?
Sometimes you can look at something like solar flares and easily see how it's most likely just before and after strong BT.  Some see it, some don't.  So in order to have an objective answer to that question I developed the Berg Timer Profile which shows exactly how something correlates with BT.

A BT profile is simply a line graph showing when an indice, like flares, occurred with reference to when the Berg Timer was 7 strength or higher.

To produce the profile I developed a spreadsheet in which I simply input daily values of the indice I want to correlate with BT and then it shows a charted profile of what the indice was doing on each day before and after BT >=7. Right now I can study 11 years of data from 2006 to 2016 to get an 11-year profile of an indice's past behavior and expected future behavior.

Using profiles makes the analysis of an indice objective and provides empirical proof, or disproof, for a BT correlation.  One can look at a charted comparison of BT and hurricanes for instance and see that hurricanes are more likely just after a BT "7" day.  Its profile provides an objective confirmation of it.  Also, since BT "7" days sometimes occur within 12 days of each other, the profile automatically integrates multiple BT days' effect.  

Profiles do not always show a definite correlation.  Some just wiggle up and down sideways with no definite pattern.  In these cases the profile cannot be of any practical use.  It could be that there's a third factor which is making the analysis unusable.  For instance, when comparing BT to car accidents you have to remove the tendency for higher accidents to occur on holidays and weekends before the data can be compared.  And on a study of temperature you have to use the "departure from normal" value, not the real temperature, since there are seasonal influences on temperature.  

The charts below, due to a similarity impossible by chance, prove that the Berg Timer is a significant, if not major, cause of changes in solar activity, and other indices related to solar activity like Earth Length of Day, Atmospheric Angular Momentum,  Cloudiness, Geomagnetism, and Sea Level.  

The sequence of the Berg Timer's effect from the sun to the Earth's surface involves a number of indices which have been well measured by today's satellite and ground instruments.  It involves several areas of professional understanding of which I have made a good effort to learn.  I welcome feedback as to its accuracy of some of the assumptions I've made but I have tried to follow today's thinking of the specialists in each field.  Regardless of whether the sequence logic is correct, I most want to demonstrate that the Berg Timer is able to forecast all of these indices and that it shows that it is very likely a causal factor in their behavior.     

The Sequence of Berg Timer's Effect From the Sun To Earth's Surface

No. 1
SOLAR FLARES --- Solar activity bottoms at day "0" when BT >= 7.  The beginning of the cause/effect sequence and first proof of BT's effect.
The physics of the planetary positions' effect is not known.  I believe it to be an effect of the planetary positions (BT) on the solar system's interplanetary magnetic field. 

No. 2

COSMIC RAYS --- During low solar activity the Earth's magnetic field is less strong letting in cosmic rays from outer space.  Whether or not cosmic rays cause nucleation which develop clouds is controversial.  The cosmic ray argument can be read here: SUNSHINE, CLOUDS AND COSMIC RAYS.  E. Palle´ Bago´ and C.J. Butler Armagh Observatory, College Hill, BT61 9DG. Armagh, N. Ireland.
The complete paper is provided here:  http://star.arm.ac.uk/~ambn/345epb.pdf  

No. 3

MAX HUMIDITY --- Water droplets form around the cosmic ray particles, the beginning stage of cloud formation.
These first three stages occurring exactly at day "0", the day of highest Berg Timer strength in each of the 257 instances in the 10-year period.  I believe these first three stages to be proofs of BT's causation of this major physical process between the planets, the sun, and Earth. 

No. 4

CLOUDINESS --- High cosmic rays provide nucleation causing clouds.  This profile includes international cities of Tokyo, Rio, Sydney, London, and Baghdad and U.S. cities of Denver, New York, and Chicago.  This Cloudiness profile correlates positively with the Precipitation profile in the Precipitation study further down the page. 

No. 5


This is a strong profile comprising 62 U.S. and International cities.  Temperature is logically inverse to Cloudiness (above) and correlates positively with Solar Irradiance (below).  You'll find that it also logically correlates negatively to Precipitation further down the page.  Everything is fitting, demonstrating BT's scientific correlation and forecasting capabilities. 

No. 6

SUNLIGHT --- Solar Irradiance at ground level is least abundant around day "0" when solar activity is low and cosmic rays are abundant.  This is a result of cosmic rays' stimulation of cloud production.  


No. 7

ATMOSPHERIC ANGULAR MOMENTUM --- As clouds form, the atmosphere causes an increasing drag effect upon the earth body.   

No. 8

LENGTH OF DAY --- LOD peaks with AAM and cosmic rays.  Increasing cloudiness and atmospheric angular momentum slow down the rate of Earth's rotation, thus increasing the length of the day.


No. 9

Along with Length of Day there is also a correction which scientists make concerning Earth's pole motion.  BT can also forecast this indice. 

No. 10

WORLD SEA LEVELS --- This was a great surprise to me.  I thought sea levels would be different throughout the world.  But they are the same around the times of strong Berg Timer!
There are differences due to coastal and bay geography but they all basicly follow the BT's profiles of LOD and AAM.  See below more examples of Sea Levels in different parts of the world.

No. 11

Atmospheric drag causes pressure changes which push and pull ocean currents.  Evidence of this is Sea Level rise and, here to the left, Sea Surface Temperature.  Evidently the "push/pull" causes ocean waters to warm up.  When water warms it expands thus higher sea levels.  This atmosphere/ocean interraction may be not precisely understood.  But ocean temperatures all around the world rise at the same time.  Regardless of why, BT can forecast it.

This new theory of a Planetary Position Effect upon Solar Activity, Earth Atmosphere, and Earth Rotation, is published here on July 28, 2016, 4:52 PM, ET.  The Berg Timer was discovered on November 19, 1980.
It is shown that the Berg Timer can accurately forecast the logical sequence of the Sun/Earth connection, that being:

A strong daily Berg Timer value >=7, which represents the state of planetary positions, equates with
low solar flares, high cosmic rays, high cloud production,
low sunlight at the ground, low temperature,
high atmospheric angular momentum,
high length of day, high sea level, and high sea surface temperature.

This evidence shows that it is highly probable that planetary positions, as represented by the Berg Timer, cause or are at least complicit in the physics of the Sun/Earth connection.

Solar Flares, Sunspots, Ozone
Above is a chart of BT and flares so far this year.  Being able to forecast solar activity is the cornerstone of BT's capabilities since solar activity is the cause of so much of Earth's atmosphere and weather.  Flare and sunspot forecasting is becoming more and more important for our space and electrical power industry.  Knowing when solar flares will occur helps them prepare for space activity, power surges, and damage to satellites.  The chart above shows that solar flares occur just before and after strong Berg Timer days.  Some see it, some don't.  That's why I think the profiles are so great because they make it objective and not subject to sight interpretation.     


 The Flare and Sunspot Profiles to the left represent acitivity with respect to 19,401 flares and 191,717 sunspots occurring within 25 days of all 257 instances of the Berg Timer >= 7 strength  from 2006 through 2015.  Lows are made in solar activity when the BT is strong, signified by day "0".
Ozone's correlation with solar activity is shown below.  Solar radiation destroys upper level Ozone so this is why high Ozone correlates negatively here.  The Berg Timer can forecast both solar activity and ozone.

U.S. Precipitation Profiles, including Airline Delays, Lightning Deaths, and Flood

There is no standard national index of U.S. Precipitation.  So I created one.  I made three precipitation indices based on two reliable sources for daily precipitation data.  

One indice I'll call "GEO" is based on data from the Department of Energy.  It's 53 cities, plotted on the left map, which were chosen to geographically represent the whole U.S..  Separate profiles were made for West, Central, East, and All U.S.
The second indice I'll call "AP".  It's all 30 of the U.S. international airports.  With this we'll find out if there's any similarity between precipitation and airline delays.  
The data source was http://climod.unl.edu/.  The third is called "UNL" based on the same data source as "AP" but this time using 56 cities.  We'll looking to see if these two data sources agree in terms of national precipitation totals profiled by BT.

In each of the three studies the amount of precipitation for each of the cities was totaled for each day from 2006 to 2015 and combined to make a profile with respect to the 12 days before and after all of the 257 instances when the daily Berg Timer was >= 7.  

It's found that the two data sources correlate well.  The highs and lows and trends are shared with highs in the days before "0", lows around "0", and another up surge after "0".

    Microsoft Excel Chart
The "UNL" Precipitation profile above for Jan-June 2016 shows good correlation to the 10-year profile, thus proving that the 10-year BT profile could have well been used to reliably forecast 2016 precipitation.
The AP Precipitation profile above for Jan-June 2016 with the other precipitation data also shows good correlation to the 10-year profile, again proving that BT profiles can forecast with reliability.
Precipitation is obviously a factor in airline delays and it is confirmed here with the profile of AIRLINE DELAYS above.  Also, 6,768 LIGHTNING REPORTS above correlate well with the profiles of precipitation. 
Above, two major airline hubs, Dallas and New York, have profiles like the national precipitation profiles with highs before "0" day, a significant low around "0", and then another trend up after "0".  These prove again that BT profiles are a valuable and reliable tool for forecasting precipitation.  To the left is LIGHTNING DEATHS which correlates very well with the precipitation profiles.  During the 10-year period there were 310 deaths by lightning.  Finally, to the right is the 10-year profile of 22,186 FLOOD REPORTS which also comes out the same as precipitation.   


The Pacific Ocean has three Monsoon areas.  They are the Australian, Indian Summer, and West North Pacific areas.



The Indian and North Pacific areas react the same with respect to their rainfall.  The South Pacific Australian monsoon runs opposite to the North Pacific and Indian Monsoons.  All of these areas are involved in El Nino activity.  Here is BT's ability to forecast short term Pacific activity.  BT is also able to forecast long term El Nino.  Both short and long term BT correlate with warm El Nino water.  Short term chart is here and long term chart is here.

The Tornado/Berg Timer chart below so far for 2016 shows that tornadoes are most likely when BT is strong and peaking.  That huge BT day in August was the strongest since 1988.  This is when the historic flood disaster happened in Lousiana.  It's much like the Great Flood of 1927 which also occurred during a very strong BT day.

Microsoft Excel Chart



In the chart above tornadoes are most likely right around strong BT days.  At left, the 10-year profile of tornadoes proves that most tornadoes indeed occur at and around strong BT days.  This profile includes 13,732 tornado reports by the National Oceanic & Atmospheric Administration compared to all 257 instances of the Berg Timer being "7" strength or higher at day "0".
World Earthquakes
See below that quakes are most likely -8 days before and 6 days after day "0".  Least likely on day "1".  
The Italy 6.2 and Burma 6.8 quakes on Aug 25, 2016 occurred exactly during the forecasted high -8 day period for quakes.
Then again two more quakes, 5.5 and 6.1 hitting Italy on October 27, -8 days before "0".

QUAKES 2016 --- The above profile of quake numbers up until October 29, 2016 shows good correlation with the 10-year profile making a high on "-8" and low on days "2" and "3", and a strong period from "-3" to "-1".   These are pretty good proofs for BT's ability to accurately forecast future seismic activity.

Atlantic Hurricanes
Below is the profile of Atlantic Hurricanes.  This could well transform Caribbean planning for travel, boating, cruises, shipping, whatever happens in the Caribbean.  This correlation was published on my website about ten years ago.  This new profile confirms it.

The best times for travel to avoid hurricanes in the Atlantic and Carribean would be starting 7 days prior to a BT "0" day.  At that time you would be able to have a good 8-10 days for a vacation with a very low probability for hurricanes, or at least not getting a hurricane's highest wind periods.  See below chart how this profile would have kept you away from Hurricane Matthew in 2016.

This would be a great asset for travel agencies or just something everyone refers to in planning their vacation.  One can use this with the Airline Delays Profile and be even more confident of your vacation timing.



Matthew was a natural progression of strength caused by the Berg Timer.  It peaked in strength just one day before the profile forecast.
It caused hundreds of deaths in Haiti, much damage throughout the Bahamas and the eastern coast of Florida.  South Carolina had massive flooding.  The Berg Timer again proves to be a valuable and reliable forecasting tool.

Geomagnetism and Hemispheric Electrification

Electrical storms energize Earth's atmosphere.  This electrical power is monitored by NOAA POES satellites.  Geomagnetism and Hemispheric Gigawatts share similar profiles and can now be forecasted by using their BT Profiles.  This forecasting ability is a valuable tool for both space and ground electronic engineers. 

Weather Profiles for Any Location in the World
Every place in the world has it's own profile for weather.  It depends on how weather systems move in speed and direction and how they are located with respect to frequent pressure systems.  Once you have the profile for a location you can use it forever without loss in reliability.  You simply use the daily Berg Timer to input the 7 or stronger days at day "0".  Then follow the profile's highs and lows and days away from "0" to know the future weather.  That's all there is to it.  



Left are three Denver weather profiles.  If you live in Denver you now know when the probabilities are highest and lowest for precipitation, wind, and cloudiness, forever.


2016 Precipitation for Denver

So far this year there have been 13 days when BT >= 7.  Combining all of them together into a profile produces the profile to the left, the 2016 Profile for Denver Precipitation.
It has correctly forcasted several important highs and lows for precipitation so far in 2016.  The high on day "-7" hit well the highs in the area for precip, wind, and cloudiness.  It missed a good low on "-3" by only one day.  Then it hit the high right on days "-1" and "0".  Then it hit the low correctly on day "9".  Overall, it has shown good correlation to the 10-year Profile so far as of September 2016, demonstrating its forecasting ability.

You can purchase a profile for any location in the Products page.  
This is great if planning an outdoor event, any location in the world for any time in the future. 

BT Weather Profiles for U.S. & World Cities
(the weather profile for any location is free with a Berg Timer order of $49.  See Products page.)

This presentation demonstrates how well the Berg Timer can forecast weather for locations all over the world.

Two profiles are shown for each city, the 10-year profile and the 2016 profile.  You can compare the two and see how well the 10-year history was able to predict the probable 2016 weather.  You can assume that when the profiles peak that temperatures will be opposite, since precipitation is most often accompanied by lower temps.  The same is true for humidity and cloudiness which logically share highs and lows with precipitation.




The Yearly Berg Timer
Low periods in BT are indicative of drought in the United States and lows in the world economy.  High periods of yearly BT indicate low seismic activity, strong world stock markets and high precipitation.
Note that as of this writing (April 2008) BT shows that the economy will bottom during the first year of our new next president (2009). Then the economy will improve for the next year (2010), then a decline for at least the next couple years of the new president (2011, 2012).  So our next president may well end his/her presidency at an economic low and be blamed for the very bad economic situation.
The government really has little control over the economy.  It all depends on the weather and how people behave. One president or one congress does not have the means to control that factor.  The economy should be a major sour point for the president who is in office in 2009-2012. But, the president elected in 2012 will see the economy strengthen in 2015, the third year of his/her first/second term. So it goes.  If the president elected in 2012 is a first term president, he/she will be re-elected due to a strong economy at the time of re-election in 2016.
See pages devoted to each subject for more detailed forecasts.
Microsoft Excel Chart

The following written/published July 2012 ---

The Berg Timer's Long-Term Forecast correctly forecasted 2012's low precipitation, high temperatures, low interest rates, La Nina, weak economy, and weak stock market.

Hang on, this trend is not substantially broken until 2015.

The BT forecast has been published on the home page since 2001.  

Notice, in the above chart, the strong up BT cycle during the Clinton administration of 1993 through 2000, thus President Clinton's economic success due to the natural cycles. Notice in the chart below the very strong BT during Ronald Reagan's 1981-1988, thus helping him to succeed.  Then note the low BT as G.W. Bush was finishing his second term in 2008-9. Thus the economic disaster inherited by President Obama, and for which he is semi-succeeding in blaming G.W. Bush.  Then note the bottoming of BT in 2011-12, thus the difficulty President Obama is having with the current economy.

The next president will enjoy the favor of presiding over the economic recovery of 2015.

If President Obama wins in November, he will take credit for the 2015 recovery. If Governor Romney wins, the economic recovery of 2015 will result in a second term for President Romney.
If there were anything the current president could have done to stimulate the economy, don't you think he would have done it by now? He tried with the stimulus but failed.

So, to put it all in perspective, except for making some changes in domestic and foreign policies, it's an illusion to think that there is anything a president, dictator, congress, parliament, union, or federal reserve can do to alter the world economic and climatic changes accurately forecasted by the Berg Timer cycle.

See below the similarity between the Berg Timer during the Dustbowl 1930's and BT during the 2020's.
