Doppler effect Sol'Ex Sun September 10

 

I made a movie using h-alpha images from September 10th, 2026.

The movie shows the sequence from the photosphere to chromosphere and back with a range of 1 angstrom. The pop up of the filament in the photosphere is due to doppler effect and the filament has a speed of 46km/s.
