2018 January 11 Sun - AR12694
The first blue sky of 2018 shows up this morning, but the seeing is bad with strong winds. My observation is severely interrupted by the wind, bad seeing and, worst of all, bad contact of the PC Card that connects the notebook to the Imperx camera.
AR12694 is a tiny AR, with no visible sunspot. There are flares and many filaments from this AR
