What is a watery Moon?
Sometimes, the Moon looks watery or liquid, due to the ice crystals in cirrostratus, if such clouds are denser and lower.
What are Mock Moons?
Mock Moons are brilliant images of the Moon formed at some distance from the actual disc of the Moon. Mock Moons are very rare and are mirages caused by the crystals in the higher atmosphere under certain special conditions.
What are lunar rainbows?
Just as sunlight produces solar rainbows, moonlight produces lunar rainbows. Both are similar. Since moonlight is fainter in intensity, lunar rainbows are less brightly coloured and rarer than solar rainbows.
