HISTORIC GEOMAGNETIC AND SOLAR ACTIVITY
July 27, 2004: Major to severe storm conditions and strong auroral activity followed the impact of a coronal mass ejection late on July 26. Sky watchers at high, middle and low latitudes - as far south as Nevada, Utah and NORTHERN CALIFORNIA - were able to see the Northern Lights until dawn on July 27.
November 4, 2003: Sunspot region 10486 produced an X28 solar flare, the largest x-ray flare on record (see animation below).
October 29, 2003: Two powerful coronal mass ejections (from X17.2 and X10.0 solar flares) reached the Earth on October 29 and October 30, causing severe to extreme geomagnetic storm conditions (NOAA scale: G5). Spectacular auroral displays have been observed as far south as Florida, Arizona and CALIFORNIA.
