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. 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. Other astronomers, including Friedrich Winnecke, Edward Charles Pickering, Ernst Hartwig and Ernst Zinner looked for a star in this location without success.
