Geomag storm in progress

By: Susie77 , 7:23 PM GMT on January 24, 2012

CME from solar eruption yesterday hit our geomagnetic field today at 1304 UT. Moderate geomag storm is in progress.

Sorry about you having to cut and paste. I can't seem to post live links anymore. :(

I thought I would add this. I hope you like it. From Jan 24 near Tromso, Norway. No time-lapse acceleration. The aurora borealis was filmed in real time.

You're welcome, LowerCal! Years ago when I first made my aurora web pages, I saw a photo from a guy who lives in your area... Dennis Mammana, who lives in San Diego. He was kind enough to let me post one of his photos of the Nov 5 2001 geomag storm. We'll both be in Fairbanks this March, visiting a mutual friend. Hope to meet him!

Thanks for those webcam links, Susie. I have some more in my blog comments and I've added yours to the list.

I don't think this storm is strong enough to cause those types of outages; more like they are being swamped with ppl seeking info. My own pages have gotten close to 700 hits just today alone.

A Sudden Geomagnetic Impulse of 22 nT in Boulder was detected at 15:04 UTC.
A Geomagnetic Storm Watch is in effect.

CME Impact! The ACE Spacecraft chart did show a sharp change in the Bz data, just after 14:30 UTC. This refers to the relationship between the Suns magnetic field (Interplanetary Magnetic Field (IMF) and Earths magnetic field (Magnetosphere). A geomagnetic sudden impulse of 22 nT was detected at 15:04 UTC, and the Kiruna, Sweden magnetometer data below captures a rapid fluxuation at ground level. The solar wind data is still not available since the Proton Storm began. Geomagnetic Storm conditions will be possible in the hours ahead. You can also follow the latest information on SolarHam Facebook.

Protons are again On The Rise following the impact. See below for more details.

SUMMARY: Geomagnetic Sudden Impulse
Observed: 2012 Jan 24 1504 UTC
Deviation: 22 nT
Station: Boulder

WARNING: Geomagnetic K-index of 5 expected
Valid From: 2012 Jan 24 1445 UTC
Valid To: 2012 Jan 25 0100 UTC
Warning Condition: Onset
NOAA Scale: G1 - Minor

Kiruna Magnetometer After Impact

Strongest Radiation Storm since 2003

The solar proton flux continues at high levels. After the CME impacted Earth this morning, it reached even higher (6300 pfu) and is now the largest radiation storm since October 2003. A Strong S3 Level radiation storm remains in progress.

It may not be you, if you just had trouble today. I looked at four links at LowerCal's last night with no problem. Now, only one of the sites will load.

This morning, NWS, SPC, and assorted NOAA sites have been either intermittent or not available. I'm wondering if the solar storm is the reason?
