We obtained further imaging of the optical counterpart to GRB 260903A (Brunet et al., GCN 45499) reported in GCN 45501. The source exhibited a positional drift of ~7 arcseconds within ~2 hr. We find that the optical detection is consistent with a known MP object 2000 OQ52, as queried using the IMCCE SkyBot online service (Berthier et al., 2016) via its cone-search API.
We apologise for any inconvenience caused.
