Solar Discs, HA & CaK | Feb 2nd 2020

[MalVeauX]

Heya,

Finally had a clear day, but seeing was fairly lousy. Was seeing limited even with a 120mm aperture today, plus wind. SSM reported an obvious downward trend as seeing got worse and worse, so I was not anywhere near where I typically would want to be. But, like fishing, even a bad day is a good day out under our star.
