    The Fisherman and the Full Omega Moon

    On the evening of November 8, 2022, I waited for the full Moon to rise
    above the sea off the coast of Palermo, Sicily (Italy), not knowing
    exactly what I’d see. Before long I saw this stunning, salmon-colored
    moon showing a mirage phenomenon referred to as “ Etruscan Vase”
    or “Omega," since it resembles both the Grecian vase and the Greek
    letter.

    This is a type of inferior mirage that occurs when the layer of air
    just over the level of the sea is quite warm compared to layers of air
    further above. At first glance it may appear that a 2^nd moon is rising
    directly beneath the first one. In a minute or two, though, both moons
    merged, forming a reassuring circular shape. A fisherman took part in
    the scene, admiring this magical moment from the shore.

    Photo details: Nikon D7500 camera; 1/320 second exposure; f/5.6; ISO
    640; 70/300mm NIKKOR lens.

    Summary Author: Tomas Slovinsky
    Shown above is the occultation of Mars by the Moon that I
    captured from my home in Kosice, Slovakia on the morning of
    December 8, 2022. My camera was set to a focal length of 1.400 mm.
    Notice that the Red Planet appears redder and the Moon more orange on
    the right side of this multisequence image since both were nearing the
    horizon, where increasing path-length acts to extinguish the
    shorter wavelength colors in the visible spectrum (green, blue,
    violet).
