Home/BlogAs predicted, the first of two coronal mass ejections (CMEs) from the sun produced some good aurora displays last night, as far south as Arizona:

This was taken about the time the NOAA-15 satellite observed a peak activity level of “10” over the Northern Hemisphere.
Here’s a nice photo from Minnesota:

And, where the aurora always seems to be burning up the sky…Fairbanks, Alaska:

From Finland:

And another one from Minnesota (uff da!):

Finally, here’s the source of the CME, sunspot 2158, as photographed by Sergio Castillo a day after it unleashed the “storm”:

Hopefully, with the second CME event storm arriving today, there could be another good display tonight.
sorry, Doug, but you are beginning to bore me. Besides, you are waaay OT. -Roy
So far only k 5 not very strong and only for 6 hours in duration. I still think we will not exceed k 6 for this event.
Solar prolonged minimum conditions over the long haul are alive and well.
well, Salvatore, NOAA just issued a K = 6 alert:
Space Weather Message Code: WARK06
Serial Number: 246
Issue Time: 2014 Sep 12 1535 UTC
WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2014 Sep 12 1545 UTC
Valid To: 2014 Sep 13 0900 UTC
Warning Condition: Onset
NOAA Scale: G2 – Moderate
NOAA Space Weather Scale descriptions can be found at
http://www.swpc.noaa.gov/NOAAscales
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents – Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft – Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio – HF (high frequency) radio propagation can fade at higher latitudes.
Aurora – Aurora may be seen as low as New York to Wisconsin to Washington state.
c’mon guys, can’t we enjoy the beauty without making everything about global warming?
Roy I said K 6. I said I don’t think it will exceed K6. See earlier post.
It starts from 6.

OK. NOW it’s been upgraded to k=7 (or greater). 😉

I agree.
Do you know where in Arizona that photo was taken? Curious if it made it to my neighborhood!
Terrific photos – unusual colors, settings, and vantage points.
Glad I dropped by.
I think it will stay at 6.
This is a decrease in GCR almost 9%. There will be confusion in the weather.

Team drove to Nebraska. After delivering and picking up in Seward and then Lincoln started heading back towards Anderson, IN at 20:00. Looked for the aurora last night while traveling back east on I-80 across Iowa and had no luck. Still too cloudy.
I’m very pleased to uncover this website. I wanted to thank you for ones time for this fantastic read!!
I definitely appreciated every part of it and i also have you book
marked to look at new information on your blog.

OMG. Not again. ðŸ™
Hi Roy,
Thank you for the aurora pic’s. I’m using one for my desktop. Great stuff!
Have a great day!

I knew I liked you for a reason.
