Layer Cake Sunset
Explanation: On January 18 a tantalizing sunset was captured in this snapshot.
Seemingly sliced into many horizontal layers the Sun shimmered moments before it touched the horizon, setting over the Pacific Ocean as seen from the
mountaintop Las Campanas Observatory in Chile. Pink hues of filtered sunlight were created by the long sight-line through the hazy atmosphere.
But the remarkable layers correspond to low atmospheric layers of sharply different temperature and density also along the line of sight. Over a long path through each layer the rays of sunlight
are refracted strongly and create different images or mirages of sections of the
setting Sun.

Awesome... So.... is that a "LENTICULAR" Sunset, then?
Pretty colors...
Rain now, windy... no stars to look at...

Pretty sure it's football-shaped.

Just call me "geck" because "zilla" is like a last name.

This warm magnificence of setting sun gives pause at the edge of darkness of the coming night.
The sun set on the British Empire long ago, let one hope that today does not mark its setting on the American Republic.

I imagine it's a pretty good visual representation, except for the degree of magnification. What you'd see through binoculars or a low power telescope, say... but otherwise accurate color and brightness.

Yes, I like it! Reminds me of a many-layered red velvet cake! Imagine there's a smiley
here!
Well, ummm... the Sun is red in the APOD, though. Wonder if there are any striped blue suns? And blue velvet cakes?
