Nova seen in 1860 From Wikipedia, the free encyclopedia
T Boötis is believed to have been a nova. It was observed by only one person, Joseph Baxendell on 9, 11 and 22 April 1860, but has not been seen since.[2] It is located less than half a degree from Arcturus in the constellation Boötes and was at magnitude 9.75 when first seen, and magnitude 12.8 when last seen.[2] Other astronomers, including Friedrich Winnecke, Edward Charles Pickering, Ernst Hartwig and Ernst Zinner looked 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 the Galactic plane.[3] Joseph Ashbrook suggested in 1953 that it may be a recurrent nova which has been observed only once.[4]
