Solar Activity Report for 3/7/02
- ** Aurora Watch In Effect **
The Earth remains inside a high speed solar wind stream this evening.
A few aurora have been spotted and photographed over the last couple
of days, and sktwatchers in the higher latitudes should keep an eye
out for aurora. Other than that, solar activity has been low for
several days, and is likely to remain that way for at least another 24
hours. Suspot region 9845 is the only one visible that looks like it
has the potential for generating an M-class flare, and it is about to
rotate over the western limb of the solar disk. After that happens,
the solar disk will be devoid of any major sunspot groups for at least
the next day or two.
