A moonbow (also known as a moon rainbow or lunar rainbow) is a rainbow produced by moonlight rather than direct sunlight. Other than the difference in the light source, its formation is the same as for a solar rainbow: It is caused by the refraction of light in many water droplets, such as a rain shower or a waterfall, and is always positioned ...
Like most atmospheric optical phenomena, rainbows can be caused by light from the Sun, but also from the Moon. In case of the latter, the rainbow is referred to as a lunar rainbow or moonbow. They are much dimmer and rarer than solar rainbows, requiring the Moon to be near-full in order for them to be seen.
Light pillars can also form around the Moon, and around street lights or other bright lights. Pillars forming from ground-based light sources may appear much taller than those associated with the Sun or Moon. Since the observer is closer to the light source, crystal orientation matters less in the formation of these pillars.
A secondary rainbow is much fainter than a primary one because the intensity of light is reduced. Moonbows, or a lunar rainbow, are a rarer phenomenon that happens when light from the moon is ...
Roaring spring and early summer waterfalls make the central California destination one of the few spots on Earth to see moonbows, which are revealed by a full moon's light.
Conditions will be just right for the phenomenon to occur in early June.

As of 2013, 195 sinuous rilles have been identified on the Moon. [2] Vallis Schröteri in Oceanus Procellarum is the largest sinuous rille, and Rima Hadley is the only one visited by humans, on the Apollo 15 mission. Another prominent example is Rima Herigonius. Arcuate rilles have a smooth curve and are found on the edges of the dark lunar maria.
