Emission measure (EM) results applying the method by Plowman & Caspi (2020) on the original SDO/AIA data at 08:47:12 UT. Panels (a)–(d) show the EM maps integrated within the four distinct temperature bins specified in the respective labels. The white rectangle centered on (X, Y) = (41″, −94″) outlines the EUV counterpart of the UV burst, while the gray rectangle delimits a quiet region for comparison. Panel (e) contains the total EM within these two rectangles against temperature, where the associated errors are indicated as vertical lines. An animation of this figure is available online showing the time evolution from 08:35 to 09:00 UT.
