Filament 109km/s AR4478 Solex

Filament eruption near AR4478 on June 25. I repaired my Sol'Ex by James R and I completed a try out together wtih Lieven, a Helios colleague.

After taking the first scan, a filemant showed up in Ha2cb. Using JSolex, the speed is abt 109km/s

A made a couple of gif images to show the dynamics across different wavelengths; from 0,5 till 2,5A and -0,5 till -2,5A from the centre of the H-Alpha line.
