Lunar rainbow, 1844. Rainbow produced by moonlight rather than direct sunlight: '...this rare phenomenon was witnessed by a correspondent at Highfield House, Lenton, Nottinghamshire...At 7 h. 58 m. P.M. this...beautiful object was visible. It did not exhibit any of the prismatic colours, being of a silvery hue. The bow was stretched across a dense nimbus in N.E., the summit extending nearly to the zenith. Sky overcast, except a small portion in west, near to the zenith, over which thin cirrocumuli swiftly passed. The bow disappeared at 8 h. 5 m. P.M.'. From "Illustrated London News", 1844, Vol V.
