A Lunar Rainbow forms when a full moon is bright enough to have
its light refracted by raindrops just as is the case for the sun.
Moonlight is much fainter, of course, so the lunar rainbow is not
nearly as bright as one produced by sunlight.
Lunar rainbows have infrequently been observed since the time
of Aristotle or before. Victoria Falls and Livingstone Island are
the perfect places to experience such a rare event.
The lunar rainbow is best seen at times of high water – the
months of April, May, June and July.
