It was first seen in 1984,IAUC_3997 and then again in 1991.IAUC_5286 Images taken of it in 1999 were not recognized until 2006 when it was once again observed.MPEC_2006-O54 It was unexpectedly dim in each of these returns. Notes "obs_arc" Observation arc from the Minor Planet Center database covering dates from 1 September 1984 until 6 January 2022.
