Nocturnal rainbows form in the same way as daytime rainbows: by means of light reflecting and refracting in droplets of water. At night they’re sometimes called “lunar rainbows” or “moonbows.” In this time lapse video, look for the reversed secondary rainbows at 2:40 and 3:00.

There must be quite a few of leprechauns and pots of gold up there
Gorgeous! Nature never ceases to amaze.
The movement of the time-lapsed rainbow seems to coincide with the movement of the Moon? How interesting
Thanks, Dom.
Ben, yes, the rainbow is centered around the "antisolar" or in this case, the "antilunar" point, the point opposite the moving moon.
