Exploding Solar Filament

Check out the video —   Beautiful!

FILAMENT ERUPTION: Solar activity is low, but not zero. During the early hours of Feb. 13th, a magnetic filament erupted near the sun’s SW limb. NASA’s Solar Dynamics Observatory recorded the blast (click to set the scene in motion):

The extreme UV movie shows the filament flinging itself into space followed by the formation of a “canyon of fire” marking the channel formerly occupied by the filament. The glowing walls of the canyon are formed in a process closely related to that of arcade loops, which appear after many solar flares.

As erupting magnetic filaments often do, this one launched a coronal mass ejection (CME) into space. NASA’s STEREO-A spacecraft spotted the expanding cloud, which does not appear to be heading for Earth or any other planet.

New Solar Eruption

ANOTHER ERUPTION: For the past few days, magnetic filaments have been rising and snapping all around the sun. The latest eruption occured during the late hours of April 7th, shown here in an extreme UV video from NASA’s Solar Dynamics Observatory:

A CME hurled into space by this eruption might deliver a glancing blow to Earth’s magnetic field on or about April 9th. Like a CME observed two days ago, this one was visually confused by two other clouds leaving the sun from other blast sites at about the same time: movie.
