Tried to do some observing, but the sky was still a bit murky due to Sahara
sand dust and from the forest fires in Portugal also ash and smoke
particles.
Yesterday the sky was a bit orange all day and the sun was red to orange
when visible.

Just a few satellites were observed before the sky became too opaque.
