A Scar on the Face of the Sun - 14th May

There was little to see on Sundays Sun, however a small region of plage had recently passed over the suns north eastern limb.  Rather than a new sunspot it looks to be the remains of a previous one that has rotated round again, maybe AR12650?  https://brierleyhillsolar.blogspot.co.uk/2017/04/flame-prom-and-ar12650-in-ha-11th-april.html The shot was taken with the 0.2m Airylab HaT, Double stacked Daystar Quark and the PGR Chameleon 3 camera using 2x2 binning to shorten the exposure and try and freeze the seeing better, definitely needed in the unstable atmosphere with lower than average pressure upon us.
