Southern Polar Crown - 2nd October

The one feature of interest on an otherwise relatively blank disk today was this seemingly innocuous solar polar crown.  This cloud of cool plasma is held aloft above the solar surface by magnetic fields that outline the boundary of gigantic unipolar cells near the poles.  Taken with the Skywatcher ED80, double stacked Daystar Quark and the PGR Blackfly GigE IMX249 camera.
