09.22.11 - Our increasingly active Sun produced a large CME yesterday evening and an X1.4 class flare this morning. This increased solar activity is a normal byproduct as the sun approaches solar max.
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.
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.
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.
07.07.11 - For the first time ever, SDO has captured a movie of a comet streaking directly in front of the sun.
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.
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.
12.28.10 - The Solar and Heliospheric Observatory spots its 2000th comet: More than any comet-hunter in history.
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.
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.
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.
09.07.10 - NASA's SDO and SOHO spacecraft catches the Sun celebrating Labor Day Weekend with a coronal mass ejection on September 4.
08.10.10 - The coronal mass ejection (CME) generated by the August 7th solar flare will produce aurora.
06.27.08 - SOHO has discovered its 1500th comet, making it more successful than all the other discoverers of comets throughout history put together.
04.23.08 - Powerful starquakes ripple around the sun in the wake of mighty solar flares.
02.27.08 - Advance warning of radiation storms could give astronauts time to take cover and allow satellite operators to take protective measures.
09.26.07 - SOHO has found over 1,350 comets so far, but this one is different
05.10.07 - Journey to the center of the sun with SOHO.
08.22.06 - A beautiful flare headed off the sun and towards Earth in mid-August.
