A steeple of fire seen in the air over Ros Deala, Ireland, 24 April 1054
Annals of the Four Masters and Chronicon Scotorum, 1054: a round tower of fire was seen in the air over Ros Deala (Rossdalla, County Westmeath) on the Sunday of the feast of St George for five hours, with birds flying in and out of it. Usually read as a tornado or waterspout; a few authors have suggested an aurora. It comes sixteen months after the Chinese record of December 1052 and ten weeks before the 1054 supernova was first seen, so it cannot be the supernova. Kept on the board as a possible sign of an active Sun in these years, with a weak rating.
