Circular_text	TITLE: GCN CIRCULAR NUMBER: 38025 SUBJECT: GRB 241101A: Swift detection of a burst DATE: 24/11/01 05:57:09 GMT FROM: Simone Dichiara at Pennsylvania State University T. M. Parsotan (GSFC), S. Dichiara (PSU), R. Gupta (NASA GSFC), T. Sakamoto (AGU) and T. Sbarrato (INAF-OAB) report on behalf of the Neil Gehrels Swift Observatory Team: At 05:41:45 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 241101A (trigger=1264304). The BAT on-board calculated location is RA, Dec 204.333, +28.264 which is RA(J2000) = 13h 37m 20s Dec(J2000) = +28d 15' 49" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 15 sec. The peak count rate was ~2300 counts/sec (15-350 keV), at ~1 sec after the trigger. Due to a Sun observing constraint, Swift cannot slew to the BAT position until 17:57 UT on 2024 November 05. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is T. M. Parsotan (tyler.parsotan AT nasa.gov). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/)

Circular_text	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 A. Y. Lien (U Tampa), S. D. Barthelmy (GSFC), R. Gupta (GSFC), H. A. Krimm (NSF), S. Laha (GSFC/UMBC), A. Y. Lien (U Tampa), C. B. Markwardt (GSFC), M. J. Moss (GSFC), D. M. Palmer (LANL), T. Parsotan (GSFC), 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. The results of the batgrbproduct analysis are available at https://swift.gsfc.nasa.gov/results/batgrbcat/BAT_refined_circular/1264304

Circular_text	TITLE: GCN CIRCULAR NUMBER: 38037 SUBJECT: GRB 241101A: FRAM-ORM optical limit DATE: 24/11/02 00:15:14 GMT FROM: Martin Jelinek at Astro.Inst-AVCR,Ondrejov Martin Jelinek and Jan Strobl (ASU CAS Ondrejov, CZ), Sergey Karpov, Martin Masek, Petr Janecek, Jakub Jurysek, Jan Ebr, Ronan Cunniffe, Petr Travnicek and Michael Prouza (Institute of Physics, Prague, CZ) report: The 25cm robotic telescope FRAM-ORM at La Palma (Spain) reacted robotically to the Swift/BAT alert of GRB241101A (Parsotan et al., GCNC 38025, Lien et al., GCNC 38033), obtaining a series of unfiltered images starting at 05:42:20.6 UT, i.e. 35s post trigger. The observation sequence consisted of 40x20s exposures followed by 30x60s exposures, covering a field of view of 30 arcmin centered on the BAT position. We do not detect any new or strongly variable source in single or combined images. A deep combined image of all data taken during the first hour of follow-up (characteristic time T0+1.4ks), calibrated against Gaia DR3, reaches a 3-sigma limiting magnitude of G > 20.2 (AB).
