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

Post by 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.

Featured on front page of SpaceWeather today.

Fantastic images as always.

That FD HA looks absolutely brilliant for just 52mm of aperture. I realize it being a 6 panel mosaic helps, but still.
