206P / Barnard-Boattini is the first comet to be discovered with the help of photography . The US astronomer Edward Emerson Barnard succeeded in doing this on the night of October 13, 1892. After this observation, the comet was lost and was given the provisional designation D / 1892 T1. On October 7, 2008, the Italian astronomer Andrea Boattini succeeded in rediscovering the comet on recordings from the Mount Lemmon Survey .
Since it was first discovered, the comet had completed 20 orbits and passed Jupiter in the years 1922, 1934 and 2005 at a distance of 0.3 to 0.4 AU . On October 25, 2008, it passed through the perihelion at a distance of 1.1452 AU from the Sun, with its maximum brightness of around 20.3 mag.
