Two more Areas have been named since my last session:  AR2819 (NW quadrant) and AR2820 (close to AR2818).  However, I was unable to spot AR2819 in 540nm, but their plages could be seen in Ha and CaK.  AR2816 is barely visible in WL images, but the plages shows in Ha and Cak.  Today full disk images and close ups of the regions.
