TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5301 SUBJECT: GRB 060712: Swift detection of a burst DATE: 06/07/12 21:29:42 GMT FROM: Scott Barthelmy at NASA/GSFC J. R. Cummings (NASA/ORAU), S. D. Barthelmy (GSFC), C. Gronwall (PSU), S. T. Holland (GSFC/USRA), J. A. Kennea (PSU), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), M. Perri (ASDC), M. Stamatikos (NASA/ORAU) and L. Vetere (ASDC) report on behalf of the Swift Team: At 21:07:43 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060712 (trigger=218582). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 184.061, +35.560 {12h 16m 15s, +35d 33' 35"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows very little structure above background. This is a 6.7-sigma detection in BAT spread over ~26 sec so little is expected to be seen in the BAT lightcurve. The peak count rate was ~500 counts/sec (15-350 keV). The XRT began taking data at 21:10:47 UT, 184 seconds after the BAT trigger. The XRT on-board centroid algorithm did not find a source in the image and no prompt position is available. However analysis of the downlinked Photon Counting mode data reveals a point source at the following coordinates: RA(J2000) = 12:16:16.3, Dec(J2000) = +35:32:17.7 with an error radius of 4.2 arcseconds (90% confidence). This position is 81 arcseconds from the BAT position. UVOT was in an engineering mode, so no UVOT data are currently available.
