Parsotan (GSFC/UMBC), T. Sakamoto (AGU),\nM. Stamatikos (OSU) (i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 231110A (trigger #1195733)\n(D'Elia, et al., GCN Circ. 34977).  The BAT ground-calculated position is\nRA, Dec = 356.244, 82.630 deg which is \n   RA(J2000)  =  23h 44m 58.7s \n   Dec(J2000) = +82d 37' 48.6\" \nwith an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 34%.\n \nThe BAT light curve shows a single pulse structure with a duration of ~ 11 \nseconds and peaking ~1.5 seconds after the trigger time.\nT90 (15-350 keV) is 11.34 +- 1.56 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-1.60 to T+12.32 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.35 +- 0.11.  The fluence in the 15-150 keV band is 1.5 +- 0.1 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.63 sec in the 15-150 keV band\nis 3.4 +- 0.4 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/1195733/BA/",
