2389Solar Activity Report for 2/1/05
- Feb 1, 2005The Earth is still inside of, but exiting a coronal hole solar wind
stream. As anticipated, it didn't have much of an effect. There
really isn't much to talk about tonight. There are two small sunspot
regions visible, but neitther is a flare-producer. Perhaps worthy of
note is the fact that sunspot region 720, the source of a lot of major
flares not long ago, is making its away across the back side of the
sun, and so far, appears to be holding together pretty well. If it
stays together, which is certainly possible for a big sunspot, it
could be back for a return engagement in about a week. Stay tuned.
