The sun just gave us a present!

CHANCE OF FLARES: Giant sunspot AR2192 has a 'beta-gamma-delta' magnetic field that harbors energy for strong explosions. NOAA forecasters estimate an 85% chance of M-class flares and a 45% chance of X-flares on Oct. 24th. If an explosion does occur, it will be geoeffective because the sunspot is directly facing Earth.

Well, according to NOAA we just got one about an hour ago 2107 UTC. I don't have data on the size or the If there was a large CME. Looks like another X1 but we'll see. It will be great aurora weather.

Update from NOAA

2014-10-24 21:41 UTC R3 (Strong) Radio Blackout in progress

We said it remained a threat and here it is, producing another R3 (Strong) Radio Blackout that at the time of this posting, is still on the climb. The event began at 5:07pm EDT (2107 UTC) and is still going strong over 30 minutes later. The main communications impacts from this event are over the Pacific Ocean. In the meantime, forecasters remain vigilant to see if there is an associated coronal mass ejection. As we learn more about this event we will update this space.

Take some good welders glasses and look at the Sun, you can see the spot....saw it during the Fred Sanders Oct 2014 #2

It's neither good nor bad, it just is. The problems come from radio blackouts, the good is extra Aurora Borealis sitings. This is the largest active region since Nov. of 1990 and could produce large coronal ejections.

and i rather doubt it, but this afternoon as i was driving from greenville to raleigh in NC, i saw a color in the sky - sort of a brilliant turquoise - i have never seen before. and i am 59 years old. had my son take a picture with my phone and the picture just barely tells the story.

I don't think solar activity and those colors are related. What we are mostly receiving now are X-ray emission that disrupt high frequency radio and cause distortion in mid frequencies. If there are reasonable coronal ejections we can see the aurora Borealis in lower latitudes. This was not a very strong CME so they will have great Northern lights up north. It was an X3.1 event which is considered pretty big, but most of the main X-ray emission has been in the Pacific ocean and on the West Coast of the US. There could be more to come. This is the largest sun spot since 1990.
