T Boötisis believed to have been anova.It was observed by only one person,Joseph Baxendellon 9, 11 and 22 April 1860, but has not been seen since.[2]It is located less than half a degree fromArcturusin theconstellationBoötesand was at magnitude 9.75 when first seen, and magnitude 12.8 when last seen.[2]Other astronomers, includingFriedrich Winnecke,Edward Charles Pickering,Ernst HartwigandErnst Zinnerlooked for a star in this location without success.[3]
Despite being usually referred to as a nova, it had characteristics that set it apart from other novae - an amplitude of at least 7 magnitudes, an unusually rapid decline in brightness and a location unusually far from theGalactic plane.[3]Joseph Ashbrooksuggested in 1953 that it may be a recurrent nova which has been observed only once.[4]
