1.) Atmospherical isn't a WORD. Normally I wouldn't comment, but you have it spelled correctly in the the post you quote.
2.) This isn't a contest: concepts of burden of proof are established elsewhere, and here. When people are asking you in a post, it's usually because they're not reporting you for the same reason. Take. The. Hint.
3.) A simple moisture-laden atmospheric boundary between two wildly differing air-densities creates extreme lensing. You've seen examples in "hit shimmers" on roads, and how they distort objects on the horizon. Well... this is a lot more wide-spread, in the sky, and the distant object is both bright and FAR FAR more distant than what we see on the horizon.
I don't know if you're so unfamiliar with optics and meteorology that these are foreign concepts, or if this is more of your... playing... around. Either way, here's the olive branch:

I'm done trying to reason with you until I have some iota that you're more than a crackpot who dances on the razor edge of the this site's rules.
