2020 March 01 Sun - solar surface in H-alpha

Winds finally calm down today, and, despite the low air temperature of 31F, I am able to capture some images.

The solar surface is basically featureless, except for the general H-alpha network.

Sunspot count: group=0. sunspot=0, R=0

Telescope: Lunt LS35T with B600 blocking filter
Camera : ASI174MM
exposure: 0.40 ms
Images taken at 19:32:48 UTC and 19:50:35 UTC
cropped 320x320
approximately south is up, east to the left
