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]
