X-class solar flare

September 22, 2011 – Newly numbered NOAA Region 1302 (the bright area in the upper left of the NOAA/GOES-15 SXI image shown bottom of this post) produced an X1 (NOAA Scale R3 – Strong) flare peaking at 7:01 AM Eastern (11:01 GMT) this morning. This flare did have an impressive coronal mass ejection (CME) associated with it. However, given the location of Region 1302, this CME was not directed at Earth. Activity from this location can also increase the population of energetic protons near Earth (NOAA Solar Radiation Storm Scale), but these enhancements would be slow rising. This region is just now rotating into view, so the potential for continued activity is certainly there.

Huge new sunspot found- Earth facing on September 27, 2011This X-class solar flare is headed out to space.  The x-class solar flare is from a brand new sunspot that is HUGE.   This sunspot will be Earth facing somewhere ~ 27 Sep, long time did not see so big like this one.  Then with a CME we could see it reach the earth in as short as 16 hours with the typical time being about 2-3 days.  Todays X-class eruption is just the begining for this new sunspot!

CMEs are massive clouds of solar plasma that can streak through space at up to 3 million mph (5 million kph). CMEs that hit Earth can wreak havoc on our planet, causing disruptions in GPS signals, radio communications and power grids.

X-ray alerts are issued at the M5 (5x10E-5 Watts/m2) level, based upon 1-minute data. Large X-ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. Some large flares are accompanied by strong solar radio bursts that may interfere with satellite downlinks.
