The colorful ringed structured featured above shows a glory and Brocken Spectre. It was observed via a drone from above a mountainous area near Miaoli, Taiwan and was only visible when the Sun was directly behind the drone, which was looking downward into a fog bank. The "spectre" in the middle of the rings, best seen in the bottom photo, is the drone's shadow. This phenomenon appears when sunlight is diffracted by minute cloud droplets. Note that I wasn’t able to detect this with the naked eye as I was below the layer of clouds/fog. Photo taken on February 6, 2022.
Photo details: DJI Mavic3; 24 mm; f/2.8; 1/3200 second exposure.
