2018 May 31 Sun - AR12712
AR12712 has developed into a very complex group, with tens of sunspots. As I did not observe on May 30, I've lost track of the changes of the sunspots. It seems a new sunspot has appear to the NE end, becoming a following sunspot, and the larger sunspot of May 29, together with the small leading sunspots, are now on the leading side.
Flares are still associated with the larger sunspot in the middle, while the leading and following ends are associated with plages.
As the slow motion is still unavailable, I have to continue with push or pull the telescope to put the image in field. This task becomes very tedious when working on close-up imaging, and I have to use very short exposures (thus high gain) to avoid blur images.
Telescope: AP Starfire EDT 155 mm f/9.
stopped to 80 mm (f/17.5) for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: ASI1600MM, 4656X3520 pixels (3.8 micron), binned 2
North is up, east is to the left.
