It was considered lost after the 1909 apparition, but was rediscovered by the Czech astronomer Antonín Mrkos (Skalnate Pleso Observatory, Slovakia) on October 19, 1955 using ordinary binoculars, it was later confirmed as 18D by Leland E. Cunningham (Leuschner Observatory, University of California, Berkeley).
The comet was last seen in 1969, but was not observed in its predicted 1975 or later appartions, and is now considered lost.
