Powerfull Jan 23rd CME Arriving Now!

    Update @ 02:33 UTC Jan 25, 2012:

"Full power to the shields, Mr. Scott!"

On Jan 23, 2012 @ 03:59 UTC there was a CME produced in association with an M8.7sloar flare from Sunspot Region 1402. Here we see this CME approaching Earth's Magnetosphere on the most recent STEREO HI2
image taken at Jan 24 01:47 UTC.  Analysts at the Goddard Space Weather Lab estimated an ejection velocity of 2200 km/s getting this CME across 147,098,070 km in near record time,

Event Summary:
-Sudden Geomagnetic Impulse detected @ 15:04.
-Conditions are subsiding.
-A Kp4 Geomagnetic Storm Watch is in effect.
-S2 Solar Radiation Storm is ongoing.
-Strongest Proton Storm since 2003.
-Protons levels are now decreasing.
-WE have no Solar Wind or Density data from ACE due.
to sensor contamination from the ongoing proton event.
Read full report for all details.

Solen reported on Jan 23, 2012: ACE solar wind speed, density and temperature became invalid after approx. 06:30 UTC due to sensor contamination.

We have made a new report about the ACE satellite data issue.
You can read that report here.

   Here we can see this "Full Halo" CME as it rushes out from around the solar disk. This image was captured with the SOHO C2 telescope shortly after the CME was ejected.

  *A strong S3 Level radiation storm is still in progress.
This is the strongest proton event since 2003!

 NOAA Correction and New Data:
Issued 16:30 UTC Jan 24, 2012.
Here we see a plot of the Protons and it shows the secondary increase of 10 MeV protons as the CME arrived.
Earlier, it was stated that the current Solar Radiation Storm was the largest since May 2005, when the 10 MeV protons exceeded over 3000 PFU. This was not correct.
At the time of the earlier post, this current Storm was the biggest since January 2005, when the 10 MeV flux was 5040 pfu. After the arrival of the CME earlier today, the 10 MeV flux again increasedto approximatley 6300 pfu. This is now the largest Solar Radiation Storm since October, 2003. (The Halloween Storms)

RWC BELGIUM Tue Jan 24 2012, 1459 UT:
SHOCK IN SOLAR WIND There is a hint that the shock linked to the halo CME of Jan. 23 has just arrived (14:30 UT) in the Earth vicinity. The ACE spacecraft magnetic field measurements show a sharp excursion (up to 40 nT) for Bt. The Bz component is still positive. The shock is currently not seen in the density, speed and temperature measurements: we suspect that these measurements are currently corrupted by the proton event still in progress. We expect in the coming hours minor storm conditions to prevail.
