Sunrise eclipse

Michael Gill of Birmingham England caught this "omega" mirage of a partially eclipsed sun on 22nd September 2006 at Kourou , French Guiana.

What is the dark hourglass shape? Clue: This image proves that one of the solar images of an "omega" sunrise mirage really is upside-down. Explanation and more images here.
