Solar Activity Report for 4/18/04
- All remains quiet tonight. Actually, those four words could just
about suffice for the entire report! Outside of the solar wind
density being a bit higher than I might expect to see, there's nothing
noteworthy in the way of solar activity happening. There are three
numbered sunspot regions visible, but none of them appear to have the
potential for generating a significant flare at this time. By far the
most intriguing thing happening is the appearance of Comet Bradfield
in the SOHO C3 coronagraph images. Drop by the SOHO website and take
a peek. It's quite impressive!
