TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3166 SUBJECT: Swift Trigger 113225: P60 Observations DATE: 05/04/02 07:32:42 GMT FROM: S. Bradley Cenko at Caltech S. Bradley Cenko and Derek B. Fox report on behalf of the Caltech-NRAO- Carnegie GRB Collaboration: We have observed the field of Swift Trigger #113225 with the Palomar 60- inch telescope. Automated observations began approximately three minutes after receiving the alert. We have obtained 3 x 120 second images in the Kron R band. Visual comparison with the Digitized Sky Survey yields no new sources in the field. We estimate our (3 sigma) limiting magnitude to be R ~ 20 (calculated with reference 4 objects in the Guide Star Catalog). Further observations are planned.
