Solar Activit Report for 1/29/03
- View SourceThere's not an aurora watch in effect right now, but don't be
surprised to see one tomorrow or Saturday. A fair-sized coronal hole
has rotated into an Earth-pointing position, and we should start
picking up the solar wind gusts from it Friday or Saturday. After a
couple of days with a zero sunspot number, two sunspot regions are
beginning to rotate into view. One of them is sunspot region 536
coming around for another pass. You might remember that this was a
fairly active sunspot region the last time by, and the background
X-ray flux has risen sharply within the last 24 hours. Stay tuned to
see if there is any flare potential coming up.
