Expanding sunspot region 2242
Solar activity was low today with only a couple of C-class solar flares to report. The strongest of these solar flares was an C7.0 solar flare at 01:40 UTC from sunspot region 2242. Sunspot region 2242 continue to expand today and is now the most threatening sunspot region on the earth-facing solar disk. What can we expect from it in the days ahead?
