ERUPTIVE SOLAR FLARE YESTERDAY. “Solar activity has been fairly boring during the past few days but a surprise solar flare woke us up. A long duration C7.41 solar flare peaked today at 16:32 UTC. Sunspot region 2790 is to blame and that is a sunspot region facing Earth! Long duration solar flares are known to produce coronal mass ejections so the question is… was this an eruptive event? C7.4 solar flare. Monday, 7 December 2020 – 19:45 UTC. The answer to that question is a huge yes!“
