Thanks for taking the time to reply and sorry it has taken me so long to reply back. There is so much happening on planet earth right now it is hard to keep up with it all and that is without digging into the conspiratorial side of things. We are living in interesting times but unfortunately most people seem to just be blindly going about their lives as if everything is ok.

I had a look at the post you linked. I visited the USA a couple of years ago and that was the first time I saw a sun halo. I've seen them more since now I am paying attention.

Stay safe

Jim
