Ellerman Bomb. Panels (a) and (e): Maps of the Hα and Ca II K lines, respectively, in the far-blue wing. The location of the EB centered at (9.″8, 11.″8) is indicated with a circle. Panels (b) and (f): λ − t plot at the center of the EB for Hα and Ca II K, respectively. The vertical red line indicates the spectral position shown in panels (a) and (e), while the horizontal green line indicates the time. Panels (c) and (g): Comparison between the spectral profile of the EB (solid) and the average profile over the whole FOV of the observation (dashed) for Hα and Ca II K, respectively. Panels (d) and (h): SDO/AIA 1600 and 1700 Å channels aligned to SST. An animation of this figure is available online showing the time evolution from 08:25 to 08:35 UT.
