Wow, I sure was zapped by this solar storm last night! Good grief! We have not had one like this in quite a while. The following excerpt is taken from an email alert from www.spaceweather.com. Check archives for that page. I wonder if that is what a nuclear blast feels like in some respects.
GEOMAGNETIC STORM: A sharp gust of solar wind hit Earth’s magnetosphere today, April 5th, at approximately 0800 UT and sparked the strongest geomagnetic storm of the year. The event registered 7 on the 0-to-9 Kindex scale of magnetic disturbances. Although the storm is subsiding now, it is not over; high-latitude sky watchers should remain alert for auroras.
