TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3471 SUBJECT: GRB 050525, infrared observations DATE: 05/05/25 08:55:01 GMT FROM: Peter Garnavich at U of Notre Dame J. Rosenberg (CfA) and P. Garnavich (Notre Dame) We imaged the field of GRB 050525 (Band et al. GCN 3466) and the optical afterglow reported by Rykoff et al. (GCN 3465) with the 1.2m telescope of the Fred Whipple Observatory and Stelircam infrared imager. Imaging in J and K' began on May 25.22 (UT). Quick reduction of the K' data shows a new source not visible in the 2MASS K image at 18:32:32.61 +26:20:22 +/-1.0" (J2000) based on the USNO A-2.0 catalog. This is in agreement with the position provided by Rykoff et al. (GCN 3468) and Torii & BenDaniel (GCN 3470) given their quoted errors. The brightness is roughly K'=14. This message may be cited.
