206P/Barnard-Boattini was the first comet to be discovered by photographic means.[1] The American astronomer Edward Emerson Barnard did so on the night of October 13, 1892.

After this apparition this comet was lost and was thus designated D/1892 T1.

Ľuboš Neslušan (Astronomical Institute of the Slovak Academy of Sciences) suggests that 14P/Wolf and this comet are siblings which stem from a common parent comet.[2]

This comet was accidentally rediscovered on October 7, 2008 by Andrea Boattini in the course of the Mt. Lemmon Survey.[1] The comet has made 20 revolutions since 1892 and passed within 0.3 - 0.4 AU from Jupiter in 1922, 1934 and 2005.[3][4]
