TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3448 SUBJECT: XRF050522: Near-infrared Observations DATE: 05/05/22 12:20:19 GMT FROM: Derek Fox at CIT Derek B. Fox, Dawn Erb, and Naveen Reddy (Caltech) report: "We have observed the localization region of XRF050522 (Gotz et al., GCN 3446) with the Palomar Hale 5.0-m telescope and Wide-Field Infrared Camera (WIRC), in a 30-minute series of exposures beginning at 08:21 UT (mean epoch 02:36 after the burst). We do not detect any bright new sources by comparison to 2MASS and XDSS images of the region, and therefore estimate a limiting magnitude for the afterglow of Ks > 17.2 mag at this time."
