10.23.12 - The sun emitted a significant solar flare on Oct. 22, 2012, peaking at 11:17 p.m. EDT.
10.22.12 - Newly named sunspot AR1598 has release an M5 class solar flare. This is the same region that released an M9 flare on Oct. 20, 2012.
10.20.12 - The sun emitted a significant solar flare, an M9, peaking at 2:14 p.m. EDT on Oct. 20, 2012. The associated radio blackout, an R2, has subsided, reports NOAA.
10.08.12 - The CME release on Oct. 4, 2012 has generated a G2-level geomagnetic storm on Earth resulting in aurora in upper latitudes.
10.01.12 - The CME launched by the sun on Sept. 27 resulted in aurora dipping into the continental U.S. as far south as Maryland and Ohio on Sept. 30, 2012.
09.04.12 - On September 1, 2012, a long, whip-like filament erupted on the sun. The eruption, called a coronal mass ejection, caused aurora near Earth on September 3.
08.18.12 - An active region, just beginning to rotate into view, released an M5.6 class solar flare last night at 9:01pm EDT.
08.13.12 - On July 23, 2012, a massive cloud of solar material erupted off the sun. NASA Goddard scientists clocked the giant cloud, known as a coronal mass ejection, or CME, at speeds between 1,800 and 2,200 miles per second.
08.10.12 - SDO sees a very long, whip-like solar filament extending over half a million miles in a long arc above the sun’s surface. Part of the filament seems to break away, but its basic length and shape seem to have remained mostly intact.
07.30.12 - The sun emitted a mid-level flare, peaking at 4:55 PM EDT on July 28, 2012. This flare is classified as a M6.2 flare. M-class flares are the weakest flares that can still cause some space weather effects near Earth.
07.19.12 - The sun emitted a mid-level solar flare (M7.7) on July 19, 2012, beginning at 1:13 AM EDT and peaking at 1:58 AM.
07.15.12 - The arrival of the CME associated with the July 12, 2012 X1.4 class flare, resulted in a geomagnetic storm that caused aurora to appear in lower latitudes than usual.
07.09.12 - As it turns away from Earth, AR1515 releases an M6.9 class solar flare.
07.07.12 - Anticipated for the past week, the sun finally releases an X1.1 class solar flare late on July 6.
07.05.12 - Today's M6.1 solar flare, originating from behemoth sunspot AR1515, is the twelfth M-class flare from that region in the last 3 days.
07.04.12 - Even the sun joins in America's Fourth of July celebration, with an M5.3 solar flare.
07.03.12 - On July 2, 2012, an M5.6 class solar flare erupted from the sun, peaking at 6:52 AM EDT.
