Details:
Super solar filament again: Using a telescope equipped with a H-alpha filter it is possible to see a very long solar filament. Adding two rulers given by Guy Buhry with two different inclinations to estimate the two branches of the whole filament, it is possible to estimate the total lenght of the filament of about 1 000 000 km (400 000 + 600 000 km), a very record!
Photo details: SV60 H-alpha solar telescope equipped with a SKYnyx2.2M CCD camera. 09:05 UT.
