  • Six CMEs in 24 Hours

    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.

  • Sunspot Breakthrough

    08.24.11 - Scientists detected several sunspot regions in the deep interior of the sun, 1-2 days before they appeared on the solar disc.

  • SOHO Watches a Comet Fading Away

    07.28.11 - SOHO and EPOXI combined forces to provide observations on Comet Hartley 2 -- which appears to be an irregular comet, belching chunks of ice and losing water at a surprisingly fast pace.

  • Sungrazer Comet In Front of the Sun

  • Solstice Flare and CME - UPDATE

    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.

  • Having a Solar Blast - UPDATE

    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.

  • SOHO Spots Comet #2000

    12.28.10 - The Solar and Heliospheric Observatory spots its 2000th comet: More than any comet-hunter in history.

  • Triple Solar Eruption

    12.12.10 - Solar activity surged on Dec. 12, when the sun erupted three times in quick succession, hurling a trio of bright coronal mass ejections into space.

  • Solar Observation Mission Celebrates 15 Years

    12.01.10 - Since launch in 1995, SOHO has revolutionized what we know about the solar atmosphere and violent solar storms produced by the sun.

  • 500,000 Solar Snapshots and Counting

    09.02.10 - All told, EIT instrument aboard SOHO has amassed more than 500,000 images during its 14½ years of operation. Except for a four-month hiatus in 1998, this record has gone unbroken.
