Solar Activity Report for 11/21/04
- View Source** Aurora Watch In Effect **
The Earth is currently inside of a coronal hole high speed solar wind
stream, and that has served to kick the geomnagnetic activity level up
a bit. G-1 geomagnetic storm conditions have been observed within the
last 24 hours. Skywatchers in the higher latitudes should keep an eye
out for aurora. There are two sunspot regions visible, but neither
appears to have the ability to generate a significant flare for the
time being. There is another coronal hole that is rotating into an
Earth-pointing position, and we could be seeing solar wind gusts from
it along about the 25th.
