Just began a journey into the sites given above by open mike. Wonderful!!
It seems moon dogs are seen when you look towards the moon. We had the moon behind us. Ours was a lunar rainbow (moonbow) alright.
We'll keep a look out for moon dogs and sun dogs now though. Lots of other strange and beautiful optical weather things to see.

Lady Jean making your own rainbows is such a thrill isn't it.

dianavan, We often see moon halos but never rainbow ones. That must have been wonderful.

Guest David, your shadow glow is mentioned on one of those sites - (I think that's what they mean) as "Heiligenschein".

Bob, Can you see BEE PURPLE? True-Love has always wondered about bee purple. Cheers Joy
