GCN Circular 1495
Mike Gladders (Carnegie Observatories) and Pat Hall (Princeton/Catolica) report: "Baade 6.5m (Magellan I) observations with the TEK5 camera of the field of GRB020813 acquired on the nights of August 13 and 14, starting at 13 August 5.76583 UT, do not show any evidence for extended emission coincident with the OT position. The OT first reported by Fox et al. (GCN 1470) and confirmed as fading by us (GCN 1472) is detected as a point source in all available images. In the best-seeing late-time images, detailed below, the PSF of the OT is indistinguishable in all filters from that of other nearby point sources of similar magnitude. In these excellent seeing images, the nearest object is a star 3".86 almost due N of the OT, and presumably the possible associated object reported in GCN 1491. This star has a similar magnitude in I to the OT, but is much redder, and has a fainter companion of similar color 0".99 away that could cause it to appear extended in more typical ground-based images."
