206P/Barnard–Boattini was the first comet to be discovered by photographic means. 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.
This comet was rediscovered on October 7, 2008 by Andrea Boattini in the course of the Mt. Lemmon Survey. It was initially credited to Boattini before it was identified as Comet Barnard 3. The comet has made 20 revolutions since 1892 and passed within 0.3–0.4 AU of Jupiter in 1922, 1934 and 2005.
