It is one of 32 comets discovered by American astronomers, Carolyn and Eugene Shoemaker. Observational history The comet was discovered from the Palomar Observatory on the night of 10 January 1986.Cometography The Shoemakers' discovery was confirmed by Brian A. Skiff from the Lowell Observatory two days later.IAUC_4165 Further observations and astrometric measurements by Brian G. Marsden revealed that the new comet is also periodic.IAUC_4166 IAUC_4171 IAUC_4180 It was next recovered by Shuichi Nakano on 9 September 2002.IAUC_7969 A series of possible outbursts occurred from the comet in October 2019, which has raised its maximum brightness to 14.89 during its most recent perihelion.Bodewits_2019 Notes "obs_arc" Observation arc from the Minor Planet Center database covering dates from 10 January 1986 until 22 May 2020.
