AR2757 in High Res, Cells, Full Disc | Jan 28th 2020

[MalVeauX]

Heya,

Finally off on a day with some clear weather, Florida has been such a wet cloudy mess lately. Seeing was measuring promising this morning with some sub-arc-second averages over 1 minute, in the 0.7~0.8" sustained range for a second at a time, which is plenty enough time to nab a lot of frames at high speed. AR2757, a cycle 24 region, is decaying but is still interesting with a lovely plage area and mottling around the the poles of the region. The spot is already diminished and rapidly losing its penumbra but still has a fair sized umbra to see in any wavelength. Full discs are at critical sampling level and are mosaics with a mere 52mm aperture. There's some rather interesting large prominences on the North West limb.
