Of Barnard's other two periodic comets, the first, [[D/1884 O1]] (Barnard 1) was last seen on November 20, 1884, and is thought to have disintegrated. The last, [[206P/Barnard-Boattini]] marked the beginning of a new era in cometary astronomy, as it was the first to be discovered by photography. It was a [[lost comet]] after 1892, until accidentally rediscovered on October 7, 2008, by [[Andrea Boattini]]. |
