TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5304 SUBJECT: GRB 060712: Refined analysis of the Swift-BAT burst DATE: 06/07/13 01:47:07 GMT FROM: Scott Barthelmy at NASA/GSFC D. Hullinger (BYU-Idaho), L. Barbier (GSFC), S. D. Barthelmy (GSFC), J. Cummings (GSFC/ORAU), E. Fenimore (LANL), N. Gehrels (GSFC), H. Krimm (GSFC/USRA), M. Koss (GSFC/UMD), C. Markwardt (GSFC/UMD), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/ORAU), G. Sato (GSFC/ISAS), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC) on behalf of the Swift-BAT team: Using the data set from T-119 to T+183 sec from recent telemetry downlinks, we report further analysis of BAT GRB 060712 (trigger #218582) (Cummings, et al., GCN Circ. 5301). The BAT ground-calculated position is RA,Dec = 184.065, +35.539 deg {12h 16m 15.7s, +35d 32' 21.6"} (J2000) +- 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 9%. The lightcurve for this weak source shows approximately 3 overlapping peaks starting at T_zero and lasting unit ~T+35 sec. T90 (15-350 keV) is 26 +- 5 sec (estimated error including systematics). The time-averaged spectrum from T+0.6 to T+29.7 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.64 +- 0.32. The fluence in the 15-150 keV band is 1.3 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+16.76 sec in the 15-150 keV band is 1.7 +- 0.6 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
