CaK Full Disk 27th October

Three observations of our star this month seems like a record based on the poor weather that has hampered observations for some time now, but, this morning it was certainly nice to first of all have clear skies and secondly be able to observe the sun.  Things are quiet currently as we descend ever closer to the bowels of solar minimum, but there are still the decaying active regions with small spots and associated plage of the active regions that have graced us for a third time around the sun.  The full disk was taken with the 40mm scope at ~560mm focal length with the home brew CaK filter and the PGR Chameleon 3 camera.  Not sure these spots will survive a 4th rotation but i'm confident we will see the plage again even if it is somewhat diminished than it is now.
