I'm not sure this belongs here. Read the explanation in link. There was no spectacular fading, as the year before.

Does it also show the lack of clear nights over that period? ☺

 

Yes ... and the odd nights where I simply forgot to check!

Are these visual estimates?

 

Yes. Many people have written that photographic estimates are unreliable. That makes sense to me, unless one has a widefield monochrome camera.

I did have a try at photo estimates once and yes they were unreliable.   I have looked into astrophotometry but haven't actually tried it yet.  Though I still plan to.
