Sakamoto (AGU), M. Stamatikos (OSU)\n(i.e. the Swift-BAT team):\n  \nUsing the data set from T-239 to T+1566 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 220708A (trigger #1115156)\n(D'Elia, et al., GCN Circ. 32343).  The BAT ground-calculated position is\nRA, Dec = 103.038, 72.199 deg which is\n    RA(J2000)  =  06h 52m 09.1s\n    Dec(J2000) = +72d 11' 57.4\"\nwith an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 75%.\n  \nThe BAT mask-weighted light curve shows a peak starting from T-1 s to T+3 s.\nT90 (15-350 keV) is 4.4 +- 1.0 sec (estimated error including systematics).\n  \nThe time-averaged spectrum from T-1.55 to T+3.44 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.31 +- 0.32.  The fluence in the 15-150 keV band is 1.3 +- 0.3 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.54 sec in the 15-150 keV band\nis 0.8 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.\n  \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/1115156/BA/",
