TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4134 SUBJECT: GRB 051022: SSO40 Optical Observations DATE: 05/10/22 15:11:40 GMT FROM: S. Bradley Cenko at Caltech S. B. Cenko (Caltech), D. B. Fox (Penn State), R. McNaught and B. Peterson (RSAA/ANU) report on behalf of a larger collaboration: "We have imaged the HETE localization region for GRB 051022 (Graziani, GCN 4131) with the Siding Spring Observatory 40-inch telescope. Our observations consisted of 4 x 100 s images in R-band, taken at a mean epoch of 13:23:35 UT (~ 15.6 min after the burst). We find no new sources inside the SXC error circle when compared to the Digital Sky Survey. Our limiting magnitude, calculated with respect to several Guide Star Catalog sources in the field, is ~ R > 20.0."
