06.11.13 - NASA's Interface Region Imaging Spectrograph (IRIS) mission is scheduled to launch at 7:27 p.m. PDT (10:27 p.m. EDT) Wednesday, June 26, from Vandenberg Air Force Base in California.
06.12.13 - On June 11, 2013, at 2 p.m. EDT, the sun erupted with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites.
06.08.13 - The Solar Dynamics Observatory captures the sun emitting a M5.9 class, a mid-level solar flare, peaking at 6:49pm on June 7, 2013.
05.26.13 - On May 26, 2013 at 3:24 p.m. EDT, the sun erupted with a non-Earth directed CME traveling at 550 miles per second.
05.22.13 - The sun emitted a mid-level solar flare, an M7 class, on the morning of May 22, 2013.
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.
05.20.13 - 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.
