Soderberg (Caltech) reports on behalf of the Caltech-NRAO-Carnegie\ncollaboration:\n\n\"We observed the field of GRB050525a (GCN 3466) with HST+ACS/WFC on 12 Jun\n2005 UT (t~18 days) as part of our HST Cycle 13 program to study the\nsupernovae associated with gamma-ray bursts and X-ray flashes (GO 10135;\nPI Kulkarni).  Coincident with the afterglow position (GCN 3468), we\ndetect a point source superposed on top of a compact galaxy.  Within a 0.5\narcsec aperture, we find the host+OT system to be F625W ~ 24.2 mag (Vega).\nAdopting this value as a limit on the brightness of an associated\nsupernova, we find that the SN associated with GRB050525a is at least ~0.6\nmagnitudes fainter than SN1998bw at a comparable epoch (assuming\nnegligible host extinction).  Further observations are planned.\"",
