C7.4 solar flare
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?
Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future
Gillam, MB, Whitehorse, YT, Yellowknife, NTAnchorage, AK, Fairbanks, AK, Juneau, AK, Utqiagvik, AK
