Solar Actvity Report for 8/1/04
- All is quiet now as sunspot region 652 has rotated out of view. It
did not leave quietly, however. A massive prominence was seen to
erupt on the western limb of the solar disk, and I suspect it was in
conjunction with a long duration C8-class flare. There was a big CME
accompanying the event. While it wasn't Earth-directed, it sure
looked impressive in the SOHO coronagraph imagery. For the next few
days, expect things to remain quiet. There are two small sunspot
regions visible, but neither appear to have flare-generating potential
at the present time.
