Goddard TV Video Tape: G2011-097 -- EVE Late Phase Flares



This movie shows the flare and eruption from the previous clips, zoomed in even
more on the region of the explosion. The top row shows three AIA
channels next to a map of the Sun's surface magnetic field (observed
by SDO's Helioseismic and Magnetic Imager). Underneath these images
are two traces of the Sun's brightness as observed by the EVE
instrument, corresponding to the two left-most AIA images.

As the flare goes off, all channels brighten, so much so that
star-shaped diffraction patterns show up caused by AIA's optical
properties; these patterns cross at the locations of maximum
brightness. Then the emission from the flare site itself fades
away. An hour later, a faint high glow is seen in the 94A AIA channel
(green), revealing hot gases well above the flare site. Then the 335A
channel (blue) shows a similar set of bright structures, and finally
the 171A channel (yellow) shows these structures (most clearly as
strands shaped by the Sun's magnetic field). This afterglow, the 'EUV
late phase' of the eruptive flare, reveals that the coronal gas in the
high magnetic arches is cooling, successively showing up in AIA
filters designed to image the glow from gases at temperatures within
limited ranges.  Credit: NASA/SDO/EVE/AIA/HMI/R. Hock/LASP SDO EVE Late Phase Flares
