The cold front is weakening, and the temperature is getting up.  Moderate seeing at 5/10 and transparency dropped, I would say 4/10.

Featureless solar disc, an active region might form at the lower part of the solar disc?

20180305 0559 (UT) Sun in H-alpha

It's a cloudy day, feels like summer in terms of temperature, humidity and the sky condition.



Due to the amount of cloud, I would rather upload the video clip rather than to stack the frames.  Just to let me glimpse the surface features.
