Sun in Ha and CaK of 18.9.with no visible Sunspots with normal exposed and inverted disc
This was a rewarding imaging under windy conditions in between fast moving clouds with a large prominence at SE Limb and a long stretching Filament.There were no visible Sunspots.
However at the CaK disc when zooming in I could find at Western Limb just above equator AR 4528 exiting.
I could not find it in Ha.
I adjusted the position as seen in the Northern Hemisphere and that the prominence looks up.
