MAJOR SOLAR FLARE: Big sunspot AR1429 has unleashed another major flare. This one is the strongest yet, an X5-class eruption on March 7th at 00:28 UT. NASA's Solar Dynamics Observatory recorded the extreme UV flash. This eruption hurled a bright CME into space. First-look data from STEREO-B are not sufficient to determine if the cloud is heading for Earth. Our best guess is "probably, yes, but not directly toward Earth." A glancing blow to our planet's magnetosphere is possible on March 8th or 9th. Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare.

Yeah, actually two events.
http://www.swpc.noaa.gov/alerts/warnings_timeline.html Code: ALTPX3 Serial Number: 25 Issue Time: 2012 Mar 07 1417 UTC ALERT: Proton Event 10MeV Integral Flux exceeded 1000pfu Begin Time: 2012 Mar 07 1410 UTC NOAA Scale: S3 - Strong Potential Impacts: Radiation - Passengers and crew in high latitude, high altitude flights may experience increasing radiation exposures. Astronauts on EVA (extra-vehicular activity) are exposed to elevated radiation levels. Spacecraft - Single-event upsets to satellite operations, noise in imaging systems, and slight reduction of efficiency in solar panels are likely. Radio - Degraded or episodically blacked-out polar HF (high frequency) radio propagation. Space Weather Message Code: WATA50 Serial Number: 43 Issue Time: 2012 Mar 07 1742 UTC WATCH: Geomagnetic A-index of 50 or greater predicted NOAA Scale: Periods reaching the G3 (Strong) Level Likely Valid for UTC Day: 2012 Mar 08 Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude. Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices. Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur. Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur. Radio - HF (high frequency) radio may be intermittent. Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. Space Weather Message Code: WARK06 Serial Number: 186 Issue Time: 2012 Mar 07 1451 UTC WARNING: Geomagnetic K-Index of 6 expected Valid From: 2012 Mar 07 1451 UTC Valid To: 2012 Mar 07 2100 UTC Warning Condition: Persistence NOAA Scale: G2 - Moderate 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 Washinton state. |

I just saw a headline in a local rag about this flare. This is the first time I have seen the newz report them to the masses.
Solar flare racing toward Earth may disrupt power WASHINGTON, D.C. — An impressive solar flare is heading toward Earth and could disrupt power grids, GPS and airplane flights. Time for a false flag EMP? |

a site I check on periodically, gives NOAA warnings , if any, at the bottom.
http://www.solarham.com/ Also, Dr. Keith Strong seems to watch solar anything , like a hawk. He is usally first to ever get a video out on anything happening. |
