Sunspots today; possible auroras tomorrow and the 7th

I took this photo this afternoon. Searching online, I found that the sunspot group near the center experienced a Coronal Mass Ejection (CME) event on Tuesday, and the ions it launched should hit the Earth tomorrow, probably causing very nice auroras (and possibly disrupting some communications). Today, there was even larger CME from the same group -- in fact, the largest seen this solar cycle! -- which should hit us on Monday.

It's got to get close to a k8 to get down to NYC. Even a k7 stops short according to maps I've seen... electric_blue68 Oct 5 #1

I check in on the Aurora Forecast.

I'll see headlines: big sunspots, CME to light up many more States etc.
So far always disappointed doesn't get down this far.

Probably close to 40+ yrs apart both my parents have seen the AB!

Spaceweather.com is now saying that ejection will hit us on Sunday.

I took another photo yesterday afternoon that shows two new large sunspot groups coming around:
