Lightning Strikes

The above movie shows observations of a very peppy active region, 11967, taken on 2014 February 2. This region produced dozens of bright solar flares and hundreds of microflares. Near the beginning of the movie, there is a bright flash with two spikes emanating away from it that looks a lot like lightening.

The flashy nature of this dataset may be due to the filter used to make these observations. Hinode XRT used the med-Be filter to observe this active region. The med-Be filter blocks cooler temperature plasmas and so this movie shows the hotter portions of the active region loops. This super headed plasma doesn't exist for long and so it looks a lot like a flash of lighting.

Keywords: Flare
Filters: Be-med
