Hello, Tom!
I checked some photos in your home page. I found some
interesting refraction phenomena. The Sun mirage in the
Grand Canyon was very nice image and also the sunset in
Muskegon.
In that later picture the squared Sun is also some kind
of mirage. These distorted Sun effects .. or 'Chinese
lantern effects', how I called them by one special shape
of the setting Sun, are in the same category as the green
flashes and the mirages: refraction phenomena.
The Sun could have imaginative shapes. Some examples: square
(like in your picture), keyhole (another Sun image below
the original) and Chinese lantern (zig-zag edged Sun).
There could be also separed segments above distorted solar
disc.
In Finland the famous astrophotographer Mr. Pekka
Parviainen have photographed enormous amount of sunsets and
on his pictures there are several very strange sunsets.
Some springs ago we used hunt mirages in our observatory,
which in on the coast. In suitable warm calm wheather big
ferries to Sweden were distorted, like big towers in the
horizon.
The world of refraction is fascinating. You just need to
keep your eyes open and there is possible to catch fabulous
displays of the setting Sun or mirages..
Have you ever got the green flash? I haven't...
