 M2-flare recorded by STEREO-B at 1756 GMT on Jan. 20th Sunspot 1041 (a.k.a. "old sunspot 1039") is crackling with solar flares. Over the past few days, it has produced five M-class eruptions. The ongoing sequence of flares signals a sharp upturn in solar activity. Before this week, the last time the sun produced even a single M-class solar flare was in March 2008--almost two years ago. M-class solar flares have a moderate effect on Earth. Mainly, they boost the ionization of Earth's upper atmosphere and disturb the propagation of terrestrial radio signals. |
