Observational history
The comet was discovered from the Palomar Observatory on the night of 10 January 1986.{{r|Cometography}} The Shoemakers' discovery was confirmed by Brian A. Skiff from the Lowell Observatory two days later.{{r|IAUC_4165}}
A series of possible outbursts occurred from the comet on October 2019, which has raised its maximum brightness to 14.89 during its most recent perihelion.{{r|Bodewits_2019}}
