| Description | Cookson describes a sighting of a 'luminous vapour' rising from the earth between six and seven in the evening on 7 November 1820 in Southampton [Hampshire, England]. The vapour disappeared with a loud explosion and rumbling noise. Cookson does not know what caused the vapour, but suspects it was fire rarefied by subterranean heat or nitro-sulphurous fire. He then positsthat it could also have been an exploding meteor.
