Comet Taylor is a
) on November 24, 1915.E. E. Barnard (Yerkes Observatory, Wisconsin
, United States) observed that the comet was split into two distinct nuclei, but this was not seen after March 16.
The comet was predicted to return in 1922, but was lost (see lost comet).
In 1928 the discovery of
Comet Arend-Rigaux
.
The 1976 return was predicted by
Charles Kowal (Palomar Observatory, California
, United States) found images on photographic plates for December 13, 1976.
The comet was recovered for the returns in 1984 and 1990, and in January 1998 was observed as magnitude 12 when it was 1AU from Earth.[3][4]
There were 6 recovery images of 69P in October 2018 when the comet had a magnitude of about 20.5.3-sigma uncertainty in the comet's Earth distance will be ±6000 km.
