It’s probably been over 20 years ago, I was working at a BW-3s, central OH. We went out back middle of the day and the sky had turned straight bright purple. I was not on drugs and there were multiple other people there that saw it too, somebody else even called it to our attention. And it wasn’t close to sunset, it was the middle of the day. It only ever happened that one day and I don’t know that I’ve talked to anybody else that remembers it either.
