  • NASA Spacecraft Detect a Mars-Directed CME

    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.

  • Sun Releases Slow CME

    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.

  • NASA's SDO Observes Mid-level Solar Flare

    05.22.13 - The sun emitted a mid-level solar flare, an M7 class, on the morning of May 22, 2013.

  • NASA’s STEREO Detects a CME From the Sun

    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.

  • The Sun Sends Two CMEs Toward Mercury

    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.

  • Three Solar Eruptions in 2 Days

    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.

  • Spring Fling: Sun Emits a Mid-Level Flare

    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.

  • Solar Storm Near Earth Caused by Fast 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?

  • Sun Spits Out Two CMEs

    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.

  • Earth-Directed CME Release by Long Duration Solar Flare

    02.09.13 - A Coronal Mass Ejection was released by a long duration solar flare early on February 9, 2013.

  • The Sun Produces Two CMEs

    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.

  • A Coronal Mass Ejection Erupts From the Sun

    01.31.13 - A small, Earth-directed Coronal Mass Ejection erupted early this morning.

  • Sun Shoots Out 2 Coronal Mass Ejections

    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.

  • Sungrazing Comets as Solar Probes

    12.05.12 - On Dec. 15, 2011, NASA's Solar Dynamics Observatory captured footage of Comet Lovejoy approaching the sun. The images and data collected by NASA's solar observing fleet can help scientists learn more about the sun itself.

  • SOHO: Crucial Space Weather Mission Hits 17 Years

    12.04.12 - A joint ESA/NASA mission, SOHO has helped revolutionize our understanding of the sun's interior and complex atmosphere since it launched on Dec. 2, 1995.

  • Continuing Thanksgiving Eruptions On the Sun

    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.
