The comet was predicted to return in 1922, but was lost (see lost comet).
The 1976 return was predicted by N. A. Belyaev and V. V. Emel'yanenko and on January 25, 1977, Charles Kowal (Palomar Observatory, California, United States) found images on photographic plates for December 13, 1976.
There were 6 recovery images of 69P in October 2018 when the comet had a magnitude of about 20.5. Due to the lack of observations, when the comet is at perihelion on March 18, 2019 and 2.45AU from Earth, the 3-sigma uncertainty in the comet's Earth distance will be ±6000 km.
