2018 March 13 Sun - filament and plages in the SW sector
The solar surface has been spotless since AR12670 turned to the backside on March 04, 2018.
The filament-plage assembly is just to the south-west sector of the disc centre, but activity has subsided.
The white light images are affected by clouds, otherwise they are spotless.
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)
North is up, east is to the left.
