Twisting Plage - 24th May

These images of twisted solar plasma are regions of plage, that, in calcium light would show up as white areas on the suns disk.  In Ha they manifest themselves as these areas of solar plasma whose appearance is dictated by magnetic field lines.  A couple of rotations ago these regions had sunspots, now, the spots have decayed and just the tell tale twisted plasma is all that remains.  Taken with the 203mm Airylab HaT at ~4250mm fl with a double stacked Daystar Quark etalon, a Baader solar telecompressor and the PGR Chameleon 3 camera using 2x2 binning.
