Solar Activity Report for 5/28/02
- ** Aurora Watch In Effect **
The high speed solar wind stream still persists this evening, and the
solar wind speed is over the 600 km/sec mark. A G1-class geomagnetic
storm was in force for much of the 26th and 27th. See this link for a
nice picture of an aurora display taken in Calgary, Alberta in the
pre-dawn hours of the 26th.
Within the next day or two, the Earth should exit the high speed solar
wind stream, and conditions will return to normal. Sunspot regions
9661 and 9663 have the potential of generating M-class flares, with an
M2-class flare occurring Tuesday.
