Summary
| Description | 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. |
