Sun Stone-Yugas

What drives the all-important solar cycle depends on who you ask.  NASA’s story is still in the making.  The Sun is indisputably central to life on Earth.  When solar activity is low magnetic fields weaken and higher levels of cosmic radiations permeate the atmosphere.  Cosmic rays affect cloud formation, lightning, volcanic eruptions, and climate change.  The solar-climate link is complex, yet direct connections between lows and highs in solar activity are foundational in an array of conditions. 

The Sun’s orbit around a dual star in 24,000 years with varying exposure to universal magnetism greatly affects the solar system and mental acuity in all things, wrote Hindu sage Sri Yukteswar.  In The Holy Science, Yukteswar’s calculations of periods, or yugas, for the present 24,000-year cycle started 13,501 years ago, and is divided into a night (descending) and a day (ascending) of 12,000 years each.  The descending night ended in 499 CE, which was Teotihuacan's late classical period when the Pyramid of the Feathered Serpent (Quetzalcoatl) was built. 

Mexico’s Sun Stone represents processes of the Sun itself and the Hindu Yugas model the solar system’s orbit in the galaxy.  These two vitally important cycles interact to influence the species, climate, galactic radiations and magnetism on Earth, but are two different cycles that interact in a cycle of 24,000 years.  

The Sun Stone and Yukteswar’s yugas both use increments of 1/20th of a circle with allowances for transitions between periods.  This shared divisor enables periods of the two solar models to perfectly mesh, even though no date for the Sun Stone’s beginning has been discovered.  However, using Yukteswar’s beginning date for the present 24,000-year cycle we can see how the Hindu and Mexican cycles compare with each other and historical solar and climate changes. 

In the image of the two models combined (right), the face of the Sun in the center is surrounded by four world bearers in black and white  Twenty glyphs, each representing 1/20th of the circle, circumscribe the Sun.  Yukteswar’s yugas comprise the outer ring, with each yuga represented with a different metal and color.  Key dates are based on periods of the yugas. 

Our Sun is a variable star whose brightness periodically changes in phases. Rising levels of ultraviolet emissions in recent years have resulted in visual "whitening" of our star in recent years and may account for bleaching on the Great Barrier Reef and elsewhere.

Solar Phase Shift


After announcing on June 10 that, based on the number of sunspots (dark spots) caused by magnetic activity, a mini solar maximum had finally arrived, sunspots mysteriously plummeted to zero on July 17. The Sun remained virtually spotless for days, when it should have been explosive with sunspots, flares and coronal mass ejecta in a solar maximum. Its magnetic field was weakening and erratic.  The “mini maximum” in 2014 was so low it never happened.  The Earth’s own planetary magnetic fields continually weakened and cosmic ray levels escalated between January and June 2014, according to the European Space Agency.



The north magnetic field of Sun extended into the southern hemisphere in 2012, but the south field did not cross to the north for a full and stable reversal. This mini maximum at the 2012-end of the Maya’s long count echoed the Maunder Minimum with very low sunspots and global cooling between 1650 and 1710.  The Earth’s magnetic field has continually declined since 1599, the beginning of the Bronze yuga exactly 12,001 years after the Earth’s magnetic poles briefly reversed in the Gothenburg Magnetic Excursion 12,400 BP.  In long periods of solar and planetary cycles, weakening magnetics and rising cosmic rays comprised a highly energetic phase shift.  

Feathered Serpent’s Long Count ended in 2012.


Filament eruption engulfed the entire earth-facing hemisphere of Sun, prompting NASA to announce the potential dangers of large solar flares. Despite this spectacular eruption, the solar maximum that peaked in 2014 was one of the lowest on record. The Sun's xray emissions were so low with very high ultraviolet radiance by 2010 that the Earth's thermasphere had started shrinking.



Cosmic rays reached Space Age high with solar and planetary magnetic fields weakening.

In a 12,000-year cycle, the Earth's magnetic field began weakening in the seventeenth century and continually weakened through 2012, when the pace of magnetic north's movement toward Siberia rapidly escalated.

13,501 BP

Temperatures warmed with rapid glacial melt amid high cosmic radiations, until a cosmic impact 12,800 BP.  After the impact temperatures again cooled for 1,300 years.  Sudden cooling most likely resulted from massive volcanic eruptions.

Sri Yukteswar compared qualities of the yugas with metals.  The age of gold is 4/20s of a 12,000-year subcycle.  Silver is 3/20s, bronze is 2/20s and iron is 1/20. 


Svensmark’s cosmic ray theory of clouds and global warming looks to be confirmed

Posted on September 4, 2013 by Anthony Watts

…From a Technical University of Denmark press release comes what looks to be a significant confirmation of Svensmark’s theory of temperature modulation on Earth by cosmic ray interactions. The process is that when there are more cosmic rays, they help create more microscopic cloud nuclei, which in turn form more clouds, which reflect more solar radiation back into space, making Earth cooler than what it normally might be.

Conversely, less cosmic rays mean less cloud cover and a warmer planet as indicated here.  The sun’s magnetic field is said to deflect cosmic rays when its solar magnetic dynamo is more active, and right around the last solar max, we were at an 8000 year high, suggesting more deflected cosmic rays, and warmer temperatures. Now the sun has gone into a record slump, and there are predictions of cooler temperatures ahead This new and important paper is published in Physics Letters A. – Anthony

Danish experiment suggests unexpected magic by cosmic rays in cloud formation

…Atmospheric chemists have assumed that when the clusters have gathered up the day’s yield, they stop growing, and only a small fraction can become large enough to be meteorologically relevant. Yet in the SKY2 experiment, with natural cosmic rays and gamma-rays keeping the air in the chamber ionized, no such interruption occurs. This result suggests that another chemical process seems to be supplying the extra molecules needed to keep the clusters growing…

“The result boosts our theory that cosmic rays coming from the Galaxy are directly involved in the Earth’s weather and climate,” says Henrik Svensmark, lead author of the new report. “In experiments over many years, we have shown that ionizing rays help to form small molecular clusters. Critics have argued that the clusters cannot grow large enough to affect cloud formation significantly. But our current research, of which the reported SKY2 experiment forms just one part, contradicts their conventional view. Now we want to close in on the details of the unexpected chemistry occurring in the air, at the end of the long journey that brought the cosmic rays here from exploded stars.”


The new paper is:

Response of cloud condensation nuclei (>50 nm) to changes in ion-nucleation” H. Svensmark, Martin B. Enghoff, Jens Olaf Pepke Pedersen, Physics Letters A 377 (2013) 2343–2347.

In experiments where ultraviolet light produces aerosols from trace amounts of ozone, sulfur dioxide,and water vapor, the relative increase in aerosols produced by ionization by gamma sources is constant from nucleation to diameters larger than 50 nm, appropriate for cloud condensation nuclei. This resultcontradicts both ion-free control experiments and also theoretical models that predict a decline in the response at larger particle sizes. This unpredicted experimental finding points to a process not included in current theoretical models, possibly an ion-induced formation of sulfuric acid in small clusters.
