The attention getting rainbow shown above was captured near Modica, Sicily on March 4, 2024. It was taken at approximately 2:30 pm local time, which is the reason it appears rather low slung. Rainbows can only be observed when the Sun is no higher than 42 degrees above the horizon because, as determined from the antisolar point, the radius of a primary rainbow is 42 degrees. Thus, if the Sun is higher than this, a bow won't be detected. At 2:30 in the afternoon, the Sun is beginning to move toward the western horizon and so is now low enough (except in the summer months) for a rainbow to come into view.
