TITLE: GCN CIRCULAR NUMBER: 38033 SUBJECT: GRB 241101A: Swift-BAT refined analysis DATE: 24/11/01 13:15:57 GMT FROM: Takanori Sakamoto at AGU <tsakamoto@phys.aoyama.ac.jp> A. Y. Lien (U Tampa), S. D.

Sadaula (GSFC/UMBC), T. Sakamoto (AGU) (i.e. the Swift-BAT team): Using the data set from T-60 to T+243 sec from the recent telemetry downlink, we report further analysis of BAT GRB 241101A (trigger #1264304) (Parsotan, et al., GCN Circ. 38025). The BAT ground-calculated position is RA, Dec = 204.323, 28.233 deg which is RA(J2000) = 13h 37m 17.5s Dec(J2000) = +28d 13' 57.6" with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%. The mask-weighted light curve shows a single-pulse structure that starts at T-2 sec, peaks at T+1 sec, and ends at T+9 sec. T90 (15-350 keV) is 10.3 +- 4.5 sec (estimated error including systematics). The time-averaged spectrum from T-2.76 to T+12.86 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.79 +- 0.13. The fluence in the 15-150 keV band is 5.1 +- 0.4 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.29 sec in the 15-150 keV band is 1.4 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
