Circular_text TITLE: GCN CIRCULAR NUMBER: 36743 SUBJECT: GRB 240624A: Swift detection of a burst DATE: 24/06/24 06:10:39 GMT FROM: David Palmer at LANL N. J. Klingler (GSFC/UMBC/CRESSTII), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Neil Gehrels Swift Observatory Team: At 06:01:09 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 240624A (trigger=1238732). Swift did not slew to the location due to an observing constraint. The BAT on-board calculated location is RA, Dec 102.444, -6.543 which is RA(J2000) = 06h 49m 47s Dec(J2000) = -06d 32' 36" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a complex structure with a duration of about 5 sec. The peak count rate was ~2200 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 10:01 UT on 2024 August 15. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is N. J. Klingler (noelklin AT umbc.edu). 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: 36756 SUBJECT: GRB240624A: Fermi GBM Observation DATE: 24/06/25 07:59:09 GMT FROM: Cuán de Barra at UCD C. de Barra (UCD) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 06:01:11.37 UT on 24 June 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240624A (trigger 740901676/240624251). which was also detected by Swift BAT (N. J. Klingler et al. 2024, GCN 36743). The Fermi GBM on-ground location is consistent with the Swift BAT position. The angle from the Fermi LAT boresight is 83 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 2 s (50-300 keV). The time-averaged spectrum from T0-3.1 to T0+2.0 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.45 +/- 0.39 and the cutoff energy, parameterized as Epeak, is 90 +/- 13 keV. The event fluence (10-1000 keV) in this time interval is (7.0 +/- 0.8)E-07 erg/cm^2. The 64-ms peak photon flux measured starting from T0+0.38 s in the 10-1000 keV band is 6 +/- 1 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog: https://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html For Fermi GBM data and info, please visit the official Fermi GBM Support Page: https://fermi.gsfc.nasa.gov/ssc/data/access/gbm/"

Circular_text TITLE: GCN CIRCULAR NUMBER: 36769 SUBJECT: GRB 240624A: Swift-BAT refined analysis DATE: 24/06/26 22:29:41 GMT FROM: Amy D. M. Palmer (LANL), 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), T. Parsotan (GSFC), D. Sadaula (GSFC/UMBC), T. Sakamoto (AGU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from the recent telemetry downlink, we report further analysis of BAT GRB 240624A (trigger #1238732) (Klingler et al., GCN Circ. 36743). The BAT ground-calculated position is RA, Dec = 102.473, -6.534 deg which is RA(J2000) = 06h 49m 53.6s Dec(J2000) = -06d 32' 02.8" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 49%. The mask-weighted light curve shows a main structure with some overlapping pulses that starts at ~T-2 s and ends at ~T+6 s. The main peak occurs at ~T+1.5 s. T90 (15-350 keV) is 5.89 +- 2.25 sec (estimated error including systematics). The time-averaged spectrum from T-0.06 to T+7.04 sec is best fit by a power law with an exponential cutoff. This fit gives a photon index 0.07 +- 0.94, and Epeak of 78.3 +- 36.0 keV (chi squared 45.64 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 4.5 +- 0.6 x 10^-7 erg/cm2 and the 1-sec peak flux measured from T+0.88 sec in the 15-150 keV band is 2.2 +- 0.3 ph/cm2/sec. A fit to a simple power law gives a photon index of 1.33 +- 0.18 (chi squared 52.69 for 57 d.o.f.). 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/1238732
