TITLE: GCN CIRCULAR NUMBER: 8052 SUBJECT: GRB 080802, Swift-BAT refined analysis DATE: 08/08/03 00:12:25 GMT FROM: Scott Barthelmy at NASA/GSFC H. Krimm (GSFC/USRA), S. D. Barthelmy (GSFC), W. Baumgartner (GSFC/UMBC), J. Cummings (GSFC/UMBC), E. Fenimore (LANL), N. Gehrels (GSFC), C. Markwardt (GSFC/UMD), K. McLean (GSFC/UMD), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/UMBC), G. Sato (ISAS), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC), T. Ukwatta (GWU) (i.e. the Swift-BAT team): Using the data set from T-239 to T+388 sec from the recent telemetry downlink, we report further analysis of BAT GRB 080802 (trigger #318832) (Baumgartner, et al., GCN Circ. 8051). The BAT ground-calculated position is RA, Dec = 270.729, -32.329 deg which is RA(J2000) = 18h 02m 55.0s Dec(J2000) = -32d 19' 45.6" with an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%. The mask-weighted light curve shows several overlapping peaks starting at ~T-40 sec and ending at ~T+180. T90 (15-350 keV) is 176 +- 50 sec (estimated error including systematics). The time-averaged spectrum from T-31.1 to T+176.9 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.76 +- 0.19. 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-7.56 sec in the 15-150 keV band is 0.3 +- 0.0 ph/cm2/sec. All the quoted errors are at the 90% confidence level. Given the Galactic lon,lat being in the bulge, we can not rule out a non-GRB source for this trigger. All other factors point to a GRB.
