The greatest geomagnetic storm of the 20th Century…May 13-15, 1921…a century ago, New York City/New York State were especially hard hit

One thing is certain, we should be prepared for another massive solar storm of the magnitude of the “Carrington Event of 1859” or the great geomagnetic storm of May 1921…

"firecracker" sunspot turning towards earth – possible large solar flares

Sunspot AR1476 may have some surprises for us in the coming days, and I hope it isn’t a Carrington type event. It has already launched two CME’s yesterday. From NASA’s Spaceweather.com:…

Potential for large solar flares and CME's may be with us again soon

Readers may recall my reports on the CME’s from massive sunspot group 1429, seen below. It seems the sunspot group continues to live, and has unleashed another massive Coronal Mass…
