Coronal Mass Ejections 2012
In this article on Coronal Mass Ejections 2012 we give a NASA Video of the most recent CME and facts on this Coronal Mass Ejection and give links to NASA and NOAA Websites for more information we are also going to give a CME or Solar Flare Overview and then discuss the January 24, 2012 CME event in detail!
Coronal Mass Ejections 2012 – The January 19 – January
You can click on this link to go to the NASA Sun Earth Web page and see a video of the CME mentioned below and to research other events.
The sun erupted late on January 22, 2012 with an M8.7 class flare, an earth-directed coronal mass ejection (CME), and a burst of fast moving, highly energetic protons known as a "solar energetic particle" event. The latter has caused the strongest solar radiation storm since September 2005 according to NOAA's Space Weather Prediction Center.
Here is the first of 2 NASA Videos capturing the Solar Flare as it actually occurred. Solar Dynamics Observatory captured the flare, shown here in teal as that is the color typically used to show light in the 131 Angstrom wavelength, a wavelength in which it is easy to view solar flares. The flare began at 10:38 PM ET on Jan. 22, peaked at 10:59 PM and ended at 11:34 PM.:
NASA's Goddard Space Weather Center's models predict that the CME is moving at almost 1,400 miles per second, and could reach Earth's magnetosphere – the magnetic envelope that surrounds Earth — as early as tomorrow, Jan 24 at 9 AM ET (plus or minus 7 hours). This has the potential to provide good auroral displays, possibly at lower latitudes than normal.
This CME comes on the heels of a long duration M-class flare began erupting on the sun at 8:42 AM ET on Thursday, January 19. The flare is shown in the above movie from the Solar Dynamics Observatory in a combination of light wavelengths. An earth-directed coronal mass ejection was associated with the solar flare. NASA's Space Weather Services estimates that it is traveling at over 630 miles per second and will reach Earth some time on Saturday, January 21, when strong geomagnetic storms are possible and viewers can be on the look out for increased aurora.

The NOAA has a Space Weather Prediction Center. You can Click on this link to go directly to their webpage for up to the minute Press releases on Coronal Mass Ejections in 2012 and other Space Weather Events
At the time this article waws written it was 4;07 pm Central time on Monday January 23, 2012. Below are the current Releases on the NOAA Space Weather Prediction Website at this point in time to give you an idea of how they track and release information on Space Weather events:
2012-01-23 15:01 Geomagnetic Storm Expected Tuesday, Jan 23
As the strongest Solar Radiation Storm (S3) since May, 2005 continues, the associated Earthward-directed Coronal Mass Ejection is expected to arrive about 1400 UT (9am EST) Jan 24. SWPC has issued a Geomagnetic Storm Watch with G2 level storming likely and G3 level storming possible, with the storm continuing into Wednesday, Jan 25. All of this activity is related to a moderate (R2) Radio Blackout x-ray flare that erupted Sunday night (11pm EST). Updates will be posted here as we learn more or follow us on Facebook.
2012-01-23 07:02 Largest Solar Radiation Storm Since 2005 in Progress
The strongest Solar Radiation Storm since September, 2005 is in progress and continues to get stronger and a very fast Coronal Mass Ejection (CME) is headed towards Earth. Geomagnetic storming is a near certainty from this event, pending preliminary analysis no estimates are available yet for timing or strength of the storm. The associated solar flare peaked at the R2 (Moderate) level on January 23 at 0400 GMT (11pm Jan 22 EST). Updates will be posted here as we learn more or follow us on Facebook.
2012-01-20 16:35 G1 (Minor) Geomagnetic Storm Possible January 23
SWPC Forecasters have determined that the CME from NOAA Region 1402 near disk center yesterday will likely pass above (north) of Earth. This glancing blow will cause just G1 (Minor) Geomagnetic Storm activity. Look for the first signs of it around 1800Z (1:00 pm EST) on Sunday, January 22, with the bulk of the disturbance to occur Monday, January 23. Watch here for updates.
2012-01-19 23:10 UPDATE — CME from Center Disk Today
Following on from earlier today, an eruption from NOAA Region 1402 at 1605 UTC (11:05 EST) today included an earth-directed CME. Forecasters expect it to impact the geomagnetic field this weekend. Analysis is ongoing as to the strength of this impending disturbance. Check here for updates.
NOAA Regions 1401 and 1402, positioned near the center of the disk, dominate the x-ray imagery today. Expect additional R1 (Minor) Radio Blackouts from flares, and given their location, an eruption of a CME in the near future would certainly have an impact on the earth's magnetic field. Keep watch here through the weekend as conditions unfold.
