The sun showed a more active face today, with prominences, spots, filaments, and even flares. AR 1675 is releasing M-Class flares, and we have been able to monitor the effects on the earth's magnetic field with the magnetometer I described in my post yesterday. Seeing was a little better today than lately, and was able to get some nice images with the PSTDS. I'll be in San Francisco next week, so this blog might be quiet for a few days--unless SF gets hit by a meteorite!
