10.25.11 - A coronal mass ejection (CME) shot off the sun late in the evening of October 21 and hit Earth on October 24 at about 2 PM ET causing red aurora in the U.S.
10.04.11 - On October 2, 2011, an exceptionally bright comet headed toward the sun and disintegrated; moments later a large coronal mass ejection (CME) blew off the other side of the sun.
09.27.11 - The severe geomagnetic storm that began yesterday when a CME hit Earth's magnetic field is subsiding.
09.22.11 - Our increasingly active Sun produced a large CME yesterday evening and an X1.4 class flare this morning. This increased solar activity is a normal byproduct as the sun approaches solar max.
09.20.11 - The sun let loose with at least six coronal mass ejections (CMEs) from 7 PM ET on September 18, 2011 until 1 PM on September 19. One may impact Earth and spark aurora tomorrow.
09.12.11 - After last week's flurry of strong flares from sunspot 1283, solar activity is subsiding as this sunspot rotates over the sun's western limb. Aurora from last week's solar activity will be dancing in the sky for the next several day.
09.08.11 - The first of what will likely be several CME hits occurred this morning sparking a strong geomagnetic storm. Additional hits will occur over the weekend.
09.07.11 - Sunspot 1283 erupted with another flare yesterday that peaked at 6:20 PM ET. This was an X2.1 class flare, some four times stronger than the earlier flare.
09.06.11 - At 9:35 PM ET on Labor Day, the sun emitted an Earth-directed M5.3 class flare as measured by the GOES satellite.
08.09.11 - On Aug. 9, 2011, the sun unleashed an X6.9 class flare. Though not Earth directed, we may experience radio and communications blackouts.
08.08.11 - The August 5, 2011 arrival of the combined August 3 CMEs caused many photographers in the northern U.S. and Europe to race outside with their cameras to record the colorful skies. They were not disappointed.
08.01.11 - Active solar region 1261 let loose with a short-lived M9.3 flare on Friday Night. No Earth directed affects are expected.
07.21.11 - Astrophotographer Thierry Legault captured what might be the last picture of Atlantis in space--and it was a solar transit.
07.11.11 - NASA has just released new high-resolution videos of the solar event recorded by SDO on June 7, 2011.
07.07.11 - For the first time ever, SDO has captured a movie of a comet streaking directly in front of the sun.
06.24.11 - NOAA forecasters declare a 30-35% chance of geomagnetic storms during the next 24 hours due to a fast-moving stream of solar wind, combined with the CME expected to arrive on June 24, 2011.
06.10.11 - Earth is still waiting for the arrival of the CME unleashed June 7, 2011 but the forecasts of the glancing blow have been substantially reduced. The Sun unleashed an M-2 solar flare, an S-1 radiation storm and a spectacular coronal mass ejection in the early hours of June 7, 2011.
06.01.11 - A high speed solar wind caused geomagnetic storms over the Memorial weekend and another high speed stream may produce even more starting June 4, 2011.
04.30.11 - High Speed Solar Wind causes aurora at both poles
