Parhelia (Mock Suns) without haloes, observed in England in 1698. On this occasion the phenomenon, caused by atmospheric refraction, began at 8am when true Sun shone through watery cloud, with mock suns appearing either side, and a pink half mock sun further off. The phenomenon lasted for two hours. From 'The Beauty of the Heavens', Charles F Blunt, (London, 1845). Coloured lithograph. Photo via Newscom
