rendering of an unusual solar flare observed on april 21, 2002
(from YouTube user liyongqiang)
"recently i was wholly captured by footage showing close ups of solar flares. i then set out to edit the material (only a few seconds) to this 3 minutes clip. it includes a TRACE (http://trace.lmsal.com/POD/TRACEpod.html) rendering of an unusual solar flare observed on april 21, 2002 (near 1'30"). all materials used here are in the public domain, as the data (see http://sohowww.nascom.nasa.gov/) have been provided by projects labelling their imagery as freely distributable for noncommercial purposes. enjoy.?
