Abstract
BETWEEN 8.55 and 9.00 p.m. British Summer Time on the evening of July 31, my family and I happened to be in our garden looking towards the setting sun. The sky was blue, broken by a few wisps of feathery cloud. When two wisps passed in turn at an elevation of roughly 60–70° between us and the sun, each showed a brilliant spectrum. The colours violet, blue, green, yellow, orange and red were clearly seen, violet being on top and red below.
