Old Active Regions Around Again - 31st July

Been away for a week or so, excuse being late in posting this up here, but finally got round to getting this animation processed.  Following a 2 week journey around the sun old active region AR12265 announced its return with a bright but dynamic prominence structure on the eastern limb as magnetic fields swirled around great waves of plasma.  For once this summer the sky had some clear breaks and I was able to get a view in.  The seeing was falling, but the view through the 8" Airylab HaT revealed the subtle changes in structure over the period of this 8 minute animation. The double stacked Daystar Quark was used with the PGR Chameleon 3 recording a cadence of 4 frames a minute for the animation.  Fingers crossed some clear skies return soon so that I can see what remains of it on the face of the sun.
