Hot Flares in a Hot Wavelength
June 19, 2012
Almost 2 dozen flares were unleashed in just over two days (Apr. 21-23, 2011) from the tangled magnetic fields of active region 11195. In this wavelength of extreme ultraviolet light (94 Angstroms), the flares appear as rapid brightenings of the strong active region that moves from the left towards the center in the movie. The vertical lines are a reaction of the CCD in the telescope to the overwhelmingly bright light. What we are actually looking at is ionized iron heated to over 6 million degrees. Now that is HOT!
