CaK Full Disk 6th July

CaK-FD-colour

The weather here in the UK really hasn't been great following summer like weather in spring, and now, autumnal weather in summer.  Maybe autumn will see a return to summer?  Fortunately some late afternoon sunshine allowed me some brief views of our star.  Viewing in CaK at 60mm aperture with f16 at both the filter and chip revealed the sun has quite a lot of plage visible at the moment, and while this is only small scale it is abundant and indicative of the cycle 25 jet stream bands of magnetism sat just below the solar surface.
