Magnificent Eruption on the Sun

Source - Space Weather News for Sept. 1, 2012: http://spaceweather.com

MAGNIFICENT ERUPTION:  On August 31st, a magnetic filament on the sun erupted in spectacular fashion, producing a long-duration solar flare, a coronal mass ejection (CME) and one of the most beautiful movies of an explosion ever recorded by NASA's Solar Dynamics Observatory.  The CME propelled by the blast might deliver a glancing blow to Earth's magnetic field in the days ahead.  Check http://spaceweather.com for movies, forecasts and updates.

SOLAR FLARE ALERTS: Would you like a call when explosions on the sun are underway? Solar flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Within a very short time a beautiful prominence erupted on the upper western limb and a M1-class solar flare happened on the lower eastern limb.

Enjoy this beautiful view through various wavelengths of the AIA instrument on board NASA's Solar Dynamics Observatory.

SDO Video: X2 C2 Combo - Feb. 15, 2011

On Feb. 15, 2011 an X2 class x-ray solar flare was observed by the Solar Dynamics Observatory. Below is a video from the SDOmission2009 YouTube channel of the of the eruption:



Here is the description of the video from the SDOmission2009 page:

"The X2 flare of Feb. 15, 2011 seen by SDO (in extreme ultraviolet light) enlarged and superimposed on SOHO's coronagraph that shows the faint edge of a "halo" coronal mass ejection as it races away from the Sun. The video covers about 11 hours."

NASA SDO Video: Dazzling Duo

Below is the most recent video from SDOmission2009:



The vdeo was posted on 02/11/2011. Here is the description of the video from the YouTube page:

"As SDO observed in extreme ultraviolet light, a pair of active regions put on quite a show over a three-day period (Feb. 7-10, 2011). The magnetic field lines above the regions produced fluttering arcs waving above them as well as a couple of flares. Another pair of smaller active regions emerges and trails behind the larger ones."

SDO Sundog Mystery

One year ago, NASA's Solar Dynamics Observatory amazed observers when it destroyed a sundog en route to orbit. A new analysis of the event is shedding light on the surprising way rocket shock-waves interact with clouds.

Cool Movie: Solar Dynamics Observatory Destroys a Sundog

NASA Science News for February 18, 2010

NASA's Solar Dynamic Observatory amazed onlookers last week when it flew past a sundog and destroyed it. Videos of the event captured shock waves from the rocket billowing through the sundog, eliciting cries of delight and amazement from the crowd below.

Solar Dynamics Observatory: The 'Variable Sun' Mission

Source - NASA Science News for February 5, 2010

The Solar Dynamics Observatory (SDO), slated for liftoff on Feb. 9th, will make IMAX-quality movies of solar explosions, peer beneath the stellar surface to see the sun's inner dynamo, and--researchers hope--unravel the mysteries of solar variability.
