The sun is almost completely blank. The main driver of all weather and climate, the entity which occupies 99.86% of all of the mass in our solar system, the great ball of fire in the sky has gone quiet again during what is likely to be the weakest sunspot cycle in more than a century. The sun’s X-ray output has flatlined in recent days and NOAA forecasters estimate a scant 1% chance of strong flares in the next 24 hours. Not since cycle 14 peaked in February 1906 has there been a solar cycle with fewer sunspots. We are currently more than six years into Solar Cycle 24 and the current nearly blank sun may signal the end of the solar maximum phase. Solar cycle 24 began after an unusually deep solar minimum that lasted from 2007 to 2009 which included more spotless days on the sun compared to any minimum in almost a century.

[1] An independent review of historical records was performed for 350 years of global volcanic activity

(1650-2009) and seismic (earthquake) activity for the past 300 years (1700 to 2009) within the continental United States and then compared to the Sun’s record of sunspots as a measure of solar activity. All three data sets were examined to determine whether a relationship existed between them and if the results of such a study could be used to develop methodology for identifying future geophysical events. The preliminary results from the study have shown that there exists a strong correlation between the solar activity that causes climate changes and the Earth’s largest seismic and volcanic events. The impressive degree of correlation for global volcanic activity (>80.6%) and for the largest USA earthquakes (100% of the top 7 most powerful) vs. solar activity lows provides a basis for future estimates of the time periods and magnitudes for the largest volcanic and seismic events many decades in advance. Finally, the coincidence of the Centennial and Bi-Centennial cycles of the RC Theory showed unmistakable relationships to these largest geophysical events. The use of such a tool may provide a new and valuable method for protection of people and property located in and around high risk geologic zones. Further, a significantly increased risk is indicated during the next 20 years for volcanic and earthquake events of historic scale. Citation: Casey, John. L.
