In the past four days we have seen 3-4 Earth directed full halo coronal mass ejections occur in association with a series of M and X class solar flares. I expect to see severe geomagnetic storming at

It looks like the major to severe geomagnetic storming that I forecasted began at approximately 1800 UTC today. It was preceeded at approximately 1600 UTC by another huge X1 class solar flare and day
The Kp index peaked at a 9 for approximately 9 hours which is at severe geomagnetic storming levels! The current storm is now subsiding but with 2-3 more Earth facing coronal mass ejections currently
After a brief respite strong (Kp-7) to moderate (Kp-6) geomagnetic storming began at approximately 0000 UTC today. The latest coronal mass ejection shock wave arrived at approximately 0900 UTC, court
Sunspot group # 10693 has produced two more very large and power solar flares. An M9 occurred at approximately 1659 UTC on November 9, 2004 and an X2 at approximately 0141 UTC on November 10, 2004. B
Severe to extreme geomagnetic storming continues globally. Both of the recent M9 and X3 solar flares produced Earth facing coronal mass ejections in the last 18 hours, so more geomagnetic storming is
Our latest severe (Kp-8) to extreme (Kp-9) geomagnetic storm has come to an end. Unfortunately though the very fast moving (1000+ k/s) partial halo coronal mass ejection released by sunspot group #10
Looking at LASCO image movies of the last two coronal mass ejections I overestimated the amount that was Earth directed. The end result in our favor is that the related current geomagnetic storming i

Hello, I have a question. If Polar Cap Absorption results from high levels of protons, a charged particle, is one pole of the earth affected more than the other. Should I move to Australia ? Steve, N
Both magnetic poles and adjacent regions are negatively impacted by polar cap absorption. 73, Thomas F. Giella, KN4LF Retired Space & Atmospheric Weather Forecaster Plant City, FL, USA Grid Square EL
Butch et all, Considering you mentioned F3 layer HF propagation and PACTOR interference of PSK31 in one email I wanted to make everyone aware of another IPS Australia F3 layer .pdf file: http://www.k

Hi David, I had trouble following the article because of the way it is laid out. Page 1 ends in mid sentence and I can't find where it begins elsewhere. In any event I still get the gist of the artic
