TITLE: GCN CIRCULAR NUMBER: 6906 SUBJECT: GRB 071010C Swift-BAT detection of a burst DATE: 07/10/13 02:59:07 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings (CRESST/NASA/GSFC) for the Swift-BAT team At 22:20:22 UT on October 10, the Swift Burst Alert Telescope (BAT) triggered on GRB 071010C (trigger #293804). The burst was on the edge of the field of view (3.5% coded) and no source was found automatically onboard. A source was found during later ground analysis at a location RA, Dec 338.054, +66.159 which is RA(J2000) = 22h 32m 13s Dec(J2000) = +66d 09' 32" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single slow-rise slow-decay peak about 12 seconds long. The peak count rate was about 1000 counts/sec (15-350 keV), at ~1 sec after the trigger. Because the burst was detected on the ground, there are no prompt XRT or UVOT data.
