Sun Spt 1039 triggers solar-flare & solar tsunami
Posted by JAC on 1/18/2010, 4:02 pm
Old sunspot 1039 still has some life left in it.

Yesterday, Jan. 17th, it unleashed a strong solar flare and triggered a solar tsunami.





The eruption, which took place on the far side of the sun, was invisible from Earth; nevertheless, NASA's STEREO-B spacecraft had a great view.

STEREO-B is stationed over the sun's eastern limb where it can see things that we cannot.

Solar rotation is slowly turning sunspot 1039 back toward our planet and STEREO-B will keep an eye on it as it approaches.

Stay tuned for updates.
