AR2758 WL, HA, CaK | March 8th 2020

[MalVeauX]

Heya,

It was gloomy and clouded over this morning, but mid-afternoon there was a break between a few clouds, managed to quickly get some data on the sunspot formed in AR2758. Looks like it's still a class B sunspot dipole of cycle 25, it seems to be trying to form an penumbra, but not quite there yet. Clouds rolled in again fast, so I couldn't do any discs or anything, but I was glad to get any chance on the sunspot before I get back to work Monday.

Equipment:

120mm F10 Frac + Baader Red CCD-IR Block Filter (internal D-ERF) + PST Etalon + 10mm BF + ASI290MM (HA)
120mm F10 Frac + Baader Blue CCD-IR Block Filter (internal D-ERF) + Lunt CaK 1200 + ASI290MM (CaK)
150mm F8 Frac + 2x Barlow (F16) + Baader Red CCD-IR Block Filter (internal D-ERF) + Baader 610nm Filter + Baader 3.0 ND Filter + ASI290MM (WL)

Very best,
