It is being called by WaPo “The Biggest solar storm since 2005“. The sun erupted late on January 22nd, 2012 with an M8.7 class flare. The Solar Dynamics Observatory captured the flare as seen below.
From NASA: The coronal mass ejection CME collided with Earth’s magnetic field a little after 10 AM ET on January 24, 2012. The influx of particles from the CME amplified the solar radiation storm such that it is now considered the largest since October 2003. NOAA’s Space Weather Prediction Center has categorized it as a “strong” — or S3 (with S5 being the highest) – storm. Solar radiation storms can affect satellite operations and short wave radio propagation, but cannot harm humans on Earth. Auroras may well be visible tonight at higher latitudes such as Michigan and Maine in the U.S., and perhaps even lower.
From spaceweather.com
CME IMPACT: As expected, a CME hit Earth’s magnetic field on Jan. 24th at approximately 1500 UT (10 am EST). A G1-class geomagnetic storm is in progress now, producing bright auroras around the Arctic Circle. Sky watchers in Canada, Alaska, and states along the US-Canadian border should be alert for Northern Lights after nightfall. Tip: The hours around local midnight are often best for aurora sightings. Aurora alerts: text, voice.
In Lofoton, Norway, the CME’s arrival produced a surge in ground currents outside the laboratory of Rob Stammes:
“The expected CME arrived and showed up on my instruments at 15.10 UTC–a fantastic shockwave followed by a magnetic storm,” says Stammes. “This could be a happy day for many aurora watchers.”
Indeed, the first auroras, post-impact, have been sighted in northern Europe. Antti Pietikäinen sends this picture from Muonio in the Finnish Lapland:
“We went out with snowmobiles to wait for the incoming storm,” says Pietikäinen. “The show started slowly, but after 15mins the landscape was green! This was the first time for Thomas (pictured above) to see the Northern Lights. He was very happy.”
Damn fossil fuels.
I know these “High class flares” happen all the time – (but all the “fallout” or CME) is not always coming in our direction.
However it may be tempting for someone to say it’s “The storm before the quiet” – It is 2012 after all!?!
The current “potential” aurora position is situated more on the Russian side of the auroral oval as it was during the first front 48 hours ago. At this point (wed 01:00 UTC) the Kp index is 5 which mirrors the first front, but the aurora extension so far is not as great.
A live 3D aurora viewer is available from the Layman’s page.

Meanwhile the solar surface only displays two countable regions (LSC)
This was a huge non-event for anyone except astronomy and ham radio types. But the media has to hype a fart in a hurricane. http://www.solarham.com/
“What a wonderful world.”
Yes here we do sometimes see the Aurora very faintly but more usually the odd skyrocket. There was a fantastic display nearly twenty years ago I think. Very impressive too, better than I ever saw up on the fringe of the Arctic circle: but only visible for a few minutes, I was very lucky to catch it, purely by chance as I drove along the mountain road at about two in the morning. .
But alas at the moment we have been and still are suffering from low overcast so no fireworks for us I am afraid. So I shall go to bed instead.
Kindest Regards
The need for headlines sometimes make clever people to say silly things. What if I say, “today was the warmest day in São Paulo (where I live) since July”? Of course it is useless information, we are in summer, and July is winter! In the same way we are now in the “summer” of the solar cycle and in 2005 the Sun were heading its “winter”. In a few months this CME will be a common one. In any case, enjoy the Auroras.
Update wed 01:15 UTC: Kp index dropping to 3, with the POES auroral position shrinking quickly. The show may possibly be over? I managed to capture an image at its peak which will be available later from the Layman’s page along with an animation of the first front.
remember folks this big yellow ball has nothing to do with anything as our leader has said and he will show you un washed that man bear pig is right !!
Not another Carrington Event then.
Absolutely beautiful! Thanks Anthony. That’s the only ‘Big Green’ we should admire.
Um, was wondering to myself as I read the title, thought it was in 2003?
The influx of particles from the CME amplified the solar radiation storm such that it is now considered the largest since October 2003.
Title change needed or did I miss something?
yes some flights was diverted..(probably mostly because of the scare) but even if the proton shower was the largest in 6 years it was just 1/10 of the proton shower in 2003…. and the flare/cme was nothing very special…
But a great show here at the arctic frontiers confer nee in Tromsø:

Hope tehre is celaring tonight in NE Oregon. Snowing now…
good chance at 45N+ . WIfe’s never seen them-despite livng in
Michigan and the Yukon a bit…
“Hope There is Clearing tonight.” Ah hates trifocals,,,
Thanks, all, for the info and links.
Last views for me were in early 1989 in central WASH State while driving east on I-90.
The magnetosphere looks like it was tied in a knot before the impact, was rocking and rolling when the flare hit, and then it settled down as the impact continued:
Was there a sensor failure somewhere in there?
Forbush decrease?
Expected effect on global temps?
(Which according to UAH are going thru the freaking floor right now, BTW)
Can you give more information? Is it danerous at all? Will it affect the climate? Will it really affect sat comms and stuff as people often say? Is it very rare? What is the biggest ever recorded? Will it make Al-Gore have a bad hair day?
thanks.
Two simple questions;
1. Do these things exit at an angle perpendicular to the surface of the sun?
2. Why does it take so long for these things to reach the earth? Why don’t they travel at the speed of light?
Cheers

“…global temps?…going thru the freaking floor right now…”
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So true. A real nosedive!
Just look at the Daily global average temperature at: 14,000 ft / 600 mb (AQUA ch05) plot for January, years 2002 through 2012 on
http://discover.itsc.uah.edu/amsutemps/
Either there was a recent instrumental failure on AQUA’s cho5, or it’s getting mighty cold all over the world now.
We had a bulls eye in Halifax NS. About 7:00 am AST ( I was awoken with my UPS alarming) the power went out in a large section of our city… transformer fire…
Increase in ground currents is a little like increasing current in your electric heater – both tend to cause the same effect. Electric currents passing through liquids and gases will tend to increase the movement of matter, which in the case of air suggests increased winds etc.
Perth at this point in time is experiencing a heat wave. Any relation ship to the CME’s ? Probably.
Even if the WaPo assessment is correct (not entirely likely), the biggest geomag storm since ’05 was rather a dud by my mid-latitude standards. It was nowhere in the league of 1989 or 1958, when Alaskans had to look south to see the auroras which were over Mexico and the Cayman Islands.
So if the big event of cycle 24 is so modest, what’s that say about the cycle itself?
Not to suggest anything, but auroras were quite rare over central Europe during the Maunder Minimum.

Noting that that is an M6-Class Solar Flare and CME from August 3, 2011.
