Palmer (LANL), D. Sadaula (GSFC/UMBC),\nT. Sakamoto (AGU)(i.e. the Swift-BAT team):\n\nUsing the data set from T-240 to T+962 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 240712A (trigger #1242223)\n(Salvaggio et al., GCN Circ. 36851). The BAT ground-calculated position is\n    RA, Dec = 122.385, -37.093 deg which is\n       RA(J2000)  =  08h 09m 32.3s\n       Dec(J2000) = -37d 05' 36.3\"\nwith an uncertainty of 2.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 93%.\n\nThe BAT light curve shows a complex structure with a duration of ~ 20 sec.\nT90 (15-350 keV) is 16.45 +- 4.89 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-4.68 to T+12.59 sec is best fit by a simple power-law model.\nThe power law index of the time-averaged spectrum is 1.29 +- 0.30.\nThe fluence in the 15-150 keV band is 2.7 +- 0.5 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.24 sec in the 15-150 keV band is 0.5 +- 0.1 ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level.\n\nThe results of the batgrbproduct analysis are available at\nhttps://swift.gsfc.nasa.gov/results/batgrbcat/BAT_refined_circular/1242223\n",
