[AZ-Observing] Sunspot and Aurora

For those who do not get the AstroAlerts, you might find the following 
interesting:

"    Region 486 is a remarkable sight to behold. The sight was even more
impressive for residents of San Diego, where smoke from the fires there
allowed residents to see the two enormous sunspot complexes (Region 486 and
developing Region 488) without the aid of special protective filters. We
don't recommend people look at the sun under any circumstances without
suitable solar filters to protect the eyes. Nevertheless, we did receive a
few reports from California of the spectacular sight through the dense smoke."

"    Analysis of the most recent X10 solar flare suggests that the coronal
mass ejection associated with it could strike the Earth near 18:00 UTC on 30
October (this is equivalent to the early afternoon hours of Thursday, 30
October for North Americans). If it's late, it should still arrive before
darkness falls over North America on Thursday. As a result, observers across
North America are encouraged to watch the skies for another impressive
auroral display on Thursday night, commencing as soon as it gets dark and
ending at dawn. It is unlikely that North America will get an opportunity to
observe activity on Friday night, unless Region 486 or 488 produce another      
major solar flare with a similarly high velocity coronal mass ejection."
