Tue Sept. 2, 2025 1. " GEOMAGNETIC STORM WATCH: A geomagnetic storm watch is in effect on Sept. 2nd as Earth passes through the wake of a CME that struck yesterday. Category G1 (Minor) storms are likely with a chance of escalating to category G2 (Moderate) or G3 (Strong). High-latitude sky...

After a few days of relative quiet, the Solar Activity intensifies once again, as large groups of big to huge sunspots make their way to the front side. A) Aug. 29, 2025 " MONSTER SUNSPOTS: A phalanx of large sunspots is facing Earth. They're so large, photographers are catching them in the...

A) Aug. 16, 2025 " CO-ROTATING INTERACTION REGION: A co-rotating interaction region (CIR) is expected to hit Earth on Aug. 18th, squeezing our magnetic field between fast and slow streams of solar wind. Watch for a sudden jump in solar wind speed, density, and magnetic field (especially Bz)...

The Solar Wind is/was still elevated (over 500Km/sec) on April 24. At the same time, 2 very interesting subjects posted: " FARMERS, DID YOUR TRACTORS JUST GO CRAZY? Many modern farmers use GPS-guided tractors to plant and tend their crops. Last weekend, some of them veered off course. We've...

A) Besides the 11 (and/or 22) year cycle (based on Solar Activity), which [, as far as I know {based on about 3 years ago look up} – but I haven't kept up with the new research on that particular climate influence related topic for the period in between ...}], is not certain whether and how it...

STRONG GEOMAGNETIC STORM (NOW): A strong G3-class geomagnetic storm is underway on April 16th following the arrival of a "cannibal CME." If current conditions persist, auroras could become visible across Canada and northern-tier US states during the night of April 16-17. Above...

" CME ARRIVES, BUT NO STRONG STORM: Arriving almost 24 hours late, a CME hit Earth's magnetic field on March 24th at 0038 UTC. The overdue impact did not cause a strong geomagnetic storm, as had been predicted. There is still a chance of minor G1-class storms today and tomorrow as Earth passes...
