Details:
Lunt60, Neptune-M camera. Protagonist of these days on the Sun are the big prominences on West (right) border, really just sections of a long "vertical" filament involving N and S hemispheres. It is in turn a section of a giant horseshoe-shaped filament stretching approximately on a North parallel, a meridian (now on W border) and finally a South parallel: An extreme example of magnetic field lines stretched by the faster Sun rotation on equator, a situation typical of a solar maximum period.
