The on-ground calculated location, using the Fermi GBM trigger data, is RA = 287.5, Dec = 42.5 (J2000 degrees, equivalent to J2000 19h 10m, 42d 30'), with a statistical uncertainty of 1.6 degrees. The angle from the Fermi LAT boresight is 41.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 38536 SUBJECT: GRB 241207A: EIRSAT-1 GMOD Detection DATE: 24/12/11 14:44:53 GMT FROM: Caimin McKenna at University College Dublin C. McKenna, D. Murphy, C. de Barra, A. Ulyanov, P. McDermott, M. Doyle, R. Dunwoody, J. Mangan, G. Finneran, G. Corcoran, L. Cotter, A. Empey, J. Fisher, F. Gibson Kiely, J. Thompson, D. McKeown, A. Martin-Carrillo, L. Hanlon, S. McBreen, on behalf of the EIRSAT-1 team: EIRSAT-1 reports the tentative detection of the long gamma-ray burst GRB 241207A by the Gamma-ray Module (GMOD) instrument, which was also detected by Fermi GBM (GCN 38454). The detection was made starting at 24-12-07 08:54:08.1 UTC. The GMOD light curve for GRB 241207A with 1.2s binning shows a long burst with multiple pulses. The timing of the pulses is in broad agreement with those seen in the Fermi GBM lightcurve. The spacecraft location at the time of detection was 4.325 N, 19.089 E at an altitude of 460.2 km. The GMOD light curve for this event can be found here: https://grb.eirsat1.ie/241207A/241207A_LC_onboard_preliminary.png EIRSAT-1 is Ireland’s first satellite (Doyle et al. Proceedings of the 4th SSEA, 2022). It is a 2U CubeSat and carries onboard a number of experiments including the Gamma-Ray Module (GMOD), a novel, compact, gamma-ray detector (Murphy et al, Experimental Astronomy, 53, 961–990, 2022). GMOD consists of a 25 mm × 25 mm × 40 mm Cerium Bromide scintillator coupled to SiPMs and is designed to detect gamma-ray bursts in the ~ 60 keV - 1.5 MeV range. EIRSAT-1 was developed in University College Dublin with support from ESA’s Fly Your Satellite! programme and was launched on 1st December 2023.

Reva (FAI), M. Krugov (FAI), A. Pozanenko (IKI) report on behalf of IKI-GRB-FuN: We performed optical observations of GRB 241207A (Fermi GBM team, GCN 38454; V.Lipunov et. al, GCN 38459; McKenna et. al, GCN 38536) in the R filter with 1-meter Zeiss-1000 telescope of Tien-Shan observatory (TSHAO). The observations began on 2024-12-07 13:04:43 UT, i.e. ~0.17 days since trigger. Using STDWeb (Karpov, 2024) ZOGY-based image subtraction against ZTF DR7 we did not find an optical candidate transient in the median stacked images of the fields: FieldID RA Dec Width Height (hr) (deg) (arcmin) 1 19:15:05 +42:01:05 19.03 19.03 2 19:09:58 +42:29:55 19.03 19.03 The preliminary upper limits are as follows: Date UT start t-T0 Exp.
