TITLE: GCN CIRCULAR NUMBER: 7924 SUBJECT: GRB 080702B : Burst detected in BAT during Swift slew DATE: 08/07/02 20:18:23 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift Jay R. Cummings (NASA/UMBC), A. Copete (Harvard), J. Grindlay (Harvard), D. Palmer (LANL), for the Swift-BAT and BATSS teams At 01:10:41, Swift-BAT observed GRB 080702B. The burst occurred during a preplanned Swift slew maneuver. The rate increase was noted during a routine check of the counting rates for missed out- of-field and slew bursts. A GRB candidate was automatically detected by the BAT Slew Survey (BATSS) with 5.9 sigma in the S band (15-50 keV) and 6.5 sigma in the B band (15-150keV). The burst profile is FRED-like with ~3sec rise and ~30sec decay. The peak count rate is 0.05cts/sec (S band) and 0.04cts/sec (B band). BATSS automated analysis measured T90 = 10.5sec and T50 = 5.5sec, and a position RA = 23h 42m 24s, DEC = -05d 29' 23" with a 90% confidence radius of 6.4arcmin. Further ground analysis of this GRB yielded a location RA, Dec 355.616, -5.424 (J2000) or RA = 23h 42m 27.8s Dec = -05d 25' 26.4" with an estimated error radius of 3 arcmin. A Swift TOO request was submitted, and Swift/XRT and UVOT began observing at about 18:30, approximately 17.3 hours after the burst.
