Ukwatta (GWU) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry\ndownlink, we report further analysis of BAT GRB 090708 (trigger #356776)\n(Krimm, et al., GCN Circ. 9621).  The BAT ground-calculated position is\nRA, Dec = 154.632, 26.616 deg which is\n   RA(J2000)  =  10h 18m 31.7s\n   Dec(J2000) = +26d 36' 58.7\"\nwith an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 27%.\n\nThe main pulse began at T-2 sec, peaked at ~T+4 sec and decayed by\n~T+16 sec. There is a hint of some low-level emission out to ~T+100 sec.\nAt T+160 sec, a pre-planned slew took the burst out of the BAT field of\nview. T90 (15-350 keV) is 15.0 +- 3.9 sec (estimated error including \nsystematics).\n\nThe time-averaged spectrum from T-1.3 to T+17.7 sec is best fit by a\nsimple power-law model.  The power law index of the time-averaged\nspectrum is 1.78 +- 0.22.  The fluence in the 15-150 keV band is\n6.9 +- 1.0 x 10-7 erg/cm2. The 1-sec peak photon flux measured from\nT+3.37 sec in the 15-150 keV band is 1.3 +- 0.3 ph/cm2/sec.  All the\nquoted errors are at the 90% confidence level.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/356776/BA/",
