Sakamoto (AGU)\n(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 241010A (trigger #1259578)\n(Dichiara, et al., GCN Circ. 37755).  The BAT ground-calculated position is\nRA, Dec = 153.367, 11.544 deg which is\n   RA(J2000)  =  10h 13m 28.1s\n   Dec(J2000) = +11d 32' 40.1\"\nwith an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 85%.\n \nThe mask-weighted light curve shows multiple emission periods. The first period\nlasts ~six seconds and displays three pulses, followed by a quiescent period, and\nthen a second emission period lasting ~15 seconds with two apparent pulses.\nT90 (15-350 keV) is 30.86 +- 1.36 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-0.04 to T+35.12 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.88 +- 0.08.  The fluence in the 15-150 keV band is 2.0 +- 0.1 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.04 sec in the 15-150 keV band\nis 4.3 +- 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\nhttps://swift.gsfc.nasa.gov/results/batgrbcat/BAT_refined_circular/1259578",
