A Lunar Rainbow

Abstract

LAST night, after 10 p.m., a thunderstorm passed over this town, travelling from west to east. When the storm had passed and the rain had almost ceased, a bright quartermoon shone brilliantly almost overhead. To the east the clouds were still very heavy and dark, and in that direction there appeared a perfect rainbow. The arc of the bow was low; it appeared as a grey band with a certain suggestion of colour, against the dark leaden sky.
