Lovely Eruption & M-Flare from November, 2011

XRT observed this beautiful eruption and M1 flare from active region 11343 on November 9th, 2011. The lefthand movie, shown in red, was taken using the Al-poly filter and is zoomed out a bit from the one on the right to capture fainter structures away from the flare core. Al-poly is used for this because it's sensitive to somewhat cooler temperatures than the Al-med filter displayed in blue. Al-poly captures light from plamsa at around 7,000,000 Kelvin, while Al-med shows material roughly twice as hot. However, both filters are sensitive to a broad range of temperatures with some overlap between them.
