05.20.13 - Coronal mass ejections that accompanied X-class flares early last week, arrived at Earth over the weekend and sparked a geomagnetic storm and aurora.
05.17.13 - On 5:24 a.m. EDT on May 17, 2013, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space.
05.14.13 - The sun's third significant solar flare in under 24 hours -- and the strongest so far of 2013 -- peaked at 9:11 p.m. EDT on May 13, 2013.› Impacts of Strong Flares
05.03.13 - The sun emitted a mid-level solar flare on May 3. Large enough flares can disrupt radio signals, but this flare's "blackout" has already subsided.
04.25.13 - On the night of April 24 and the morning of April 25, 2013, the sun erupted with two coronal mass ejections (CMEs), solar phenomena that can send billions of tons of solar particles into space.
04.21.13 - The sun erupted three times over April 20 and 21, sending billions of tons of solar particles into space. The eruptions (called CMEs) were not Earth-directed.
04.16.13 - The CME impact on April 13 was weak but it still produced high latitude aurora. The sun emitted a mid-level flare, peaking at 3:16 a.m. EDT on April 11, 2013 accompanied by an Earth-directed CME.
03.17.13 - Friday's fast moving CME has reached Earth and sparked a mild geomagnetic storm. Will higher latitude skies be turned green for St. Patrick's Day?
03.13.13 - A coronal mass ejection (CME) began at 8:36 p.m. EDT on March 12, 2013, and may pass by three NASA satellites: Spitzer, Kepler and Epoxi. A second CME began at 6:54 a.m. EDT on March 13, 2013 and may pass Earth.
02.09.13 - A Coronal Mass Ejection was released by a long duration solar flare early on February 9, 2013.
02.07.13 - In the evening of Feb. 5, 2013, the sun erupted with two coronal mass ejections or CMEs that may glance near-Earth space.
01.31.13 - A small, Earth-directed Coronal Mass Ejection erupted early this morning.
01.24.13 - One of the two slow-moving ejections from Jan. 23 is Earth-directed. In the past, CMEs of this speed have not caused substantial geomagnetic storms.
01.14.13 - On Jan. 13, 2013, at 2:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. The CME left the sun at speeds of 330 miles per second and is expected to impact Earth around Jan. 16.
11.24.12 - On Nov. 23, 2012, at 8:54 a.m. EST, the sun released an Earth-directed, slow-moving CME. This is the third Earth-directed CME since Nov. 20.
11.22.12 - On Nov. 21, 2012, at 11:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME
11.20.12 - On Nov. 20, 2012, at 7:09 a.m. EST, the sun erupted with a coronal mass ejection.
11.16.12 - The Sun erupted with two prominence eruptions, one after the other over a four-hour period on Nov. 16, 2012, between the hours of 1 and 5 a.m. EST.
11.13.12 - On Nov. 12, 2012, the sun emitted a mid-level solar flare, an M6-class, peaking at 9:04 p.m. EST.
11.09.12 - The sun released an Earth-directed coronal mass ejection at 10:24am EST on Nov. 9, 2012.
