Wow! The Sun has become hyper-dynamic the past few days.

Solar active region 11045 has grown at an extraordinary rate the past 48 hours and has unleashed multiple solar flares including a major M6 x-ray flare on Feb. 7, 2010 at 0230 UT. Above is a photo of region 11045 taken at 2058 UT on Feb 6, 2010 during an M1.6 x-ray flare.

There have been many radio bursts as well. Below are some specimens captured on our decametric radio telescope array here in New Mexico.
