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.
05.14.13 - 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
05.10.13 - On May 10, 2013, Earth, the sun and the moon lined up to create a solar eclipse visible from the South Pacific.
05.07.13 - The Equatorial Vortex Experiment was successfully conducted on May 7 from the Marshall Islands when a NASA Terrier-Oriole sounding rocket was launched followed by the launch of a Terrier-Improved Malemute sounding rocket 90 seconds later.
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.
05.01.13 - A NASA sounding rocket supporting a study of ionosphere and its impact on radio transmissions was launched at 3:38 a.m. EDT, May 1 from Roi-Namur, Republic of the Marshall Islands.
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.
04.25.13 - A NASA-funded sounding rocket mission will launch this spring to observe the formation of electrical storms in Earth's upper atmosphere that can negatively affect satellite communication and global positioning signals.
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.
03.05.13 - A blended SDO image of an erupting solar filament earned second place in Wikimedia Commons’ “Picture of the Year 2012” contest.
02.20.13 - Over the course of Feb. 19-20, 2013, scientist watched a giant sunspot form in under 48 hours.
02.09.13 - A Coronal Mass Ejection was released by a long duration solar flare early on February 9, 2013.
