Solar Activity Report for 7/23/02
- All is fairly quiet this evening. Suspot region 119 looks like it has
the potential to fire off a big flare, but it has been quiet so far.
Its going to have to hurry if it wants to do anything, as it is just
about to rotate over the western limb of the solar disk. The eastern
half of the solar disk is just about void of sunspots right now, so we
could see the sunspot numbers drop pretty soon. Sunspot region 132 is
growing rapidly and merits watching. A small coronal hole is rotating
into view, and could be a factor later on in the week.
