There was a lot of excitement in the solar community this week due to a series of solar outbursts directed at the earth, some massive.  I actually caught the beginning of one visually on 10/28, but did not take pictures.  according to spaceweather.com a cannibal coronal mass ejection (fast moving coronal mass ejection, running into a slow moving one) hit the earth creating auroras visible as far south as 39 N in central california; detectable in cameras as far south as joshua tree. 

it was of course cloudy here so i missed it all as well as the taurid meteor shower and the new moon :(

The images above show a pretty big solar prominence i captured on 8/15/21 and have absolutely nothing to do with the events described ;)
