Solar Activity Report for 1/27/03
- The solar wind speed is slowing down after the coronal hole encounters
of the past few days. Although there was a bit of auroral activity
spotted in the high latitudes, it didn't spread any beyond that.
Activity should remain quiet for the next couple of days, until
another small coronal hole begins to make its presence known. That
should happen on or about the 30th. All of the visible sunspot
regions are in the western hemispere of the solar disk, and there
isn't anything yet that has rotated into view behind them. If the
trend continues, we should see the sunspot number start dropping over
the next few days. Sunspot region 266, the largest of the sunspots
currently visible, still has the potential of popping off a low level
M-class flare or two.
