Circular_text	TITLE: GCN CIRCULAR NUMBER: 37780 SUBJECT: GRB 241013A: Fermi GBM Final Real-time Localization DATE: 24/10/13 01:09:13 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 00:58:34 UT on 13 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241013A (trigger 750473919.357776 / 241013041). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 252.9, Dec = -33.3 (J2000 degrees, equivalent to J2000 16h 51m, -33d 17'), with a statistical uncertainty of 14.5 degrees. The angle from the Fermi LAT boresight is 55.0 degrees.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 37781 SUBJECT: GRB 241013A: a long GRB detected by INTEGRAL DATE: 24/10/13 07:01:52 GMT FROM: Diego Gotz at CEA D.Gotz (CEA, Saclay), S.Mereghetti (INAF, IASF-Milano), C.Ferrigno, E.Bozzo, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC, Versoix) and J.Borkowski (CAMK, Torun) report: a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 00:58:26 UT of 2024 October 13. The refined coordinates (J2000) are: R.A.= 275.2756 deg DEC.= -15.6302 deg with an uncertainty of 2.5 arcmin (90% c.l.). A preliminary analysis gives a peak flux of about 0.6 ph/cm2/s (20-200 keV, 2-s integration time) and a fluence in the same energy range of about 6e-7 erg/cmsq. This burst has also been detected by Fermi/GBM (GCN 37780), and its position is at 26.8° from the Fermi reported position. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html

Circular_text	TITLE: GCN CIRCULAR NUMBER: 37787 SUBJECT: GRB241013A: REM observations DATE: 24/10/14 22:11:58 GMT FROM: Matteo Ferro at INAF-OAB M. Ferro, S. Campana, Y.-D. Hu, R. Brivio, P. D’Avanzo, S. Covino, and D. Fugazza (INAF-OAB) report on behalf of the REM team: We observed the field of GRB 241013A, detected by Fermi GBM (Fermi GBM Team GCN 37780) and INTEGRAL (Gotz et al. GCN 37781), with the REM 60cm robotic telescope located at the ESO observatory of La Silla (Chile), for two consecutive nights. The observations were carried in the g, r, i, z, J, H bands, starting: (1) epoch 1 on 2024 October 13 at 01:23 UT (i.e. 24.4 minutes after the INTEGRAL trigger), and lasting for about 1 hours. (2) epoch 2 on 2024 October 14 at 00:57 UT (i.e. 1 day after the INTEGRAL trigger), and lasting for about 1 hours. We note that the field is extremely crowded due to its localization near the Galactic plane, where the extinction is significantly high, with E(B-V) = 11.8 (https://irsa.ipac.caltech.edu/workspace/TMP_QnYsQd_14990/DUST/18_20_57.1_-15_38_09.5.v0001/extinction.html) From preliminary photometry within the 90% c.l. INTEGRAL error region (2.5 arcmin) we detect a source that is not listed in the 2MASS catalog, in H band first epoch, at the following position (J2000): R.A. = 18:20:57.1 DEC. = -15:38:09.5 with a fiducial uncertainty of 3 arcsec. With magnitude: epoch (1) H = 14.9+-0.3 (Vega; against 2MASS) The source is not detected in the second epoch down to: epoch (2) H > 15.3 (Vega; against 2MASS) We note however that two PS1 sources are consistent with the candidate position, and a third one is marginally consistent, with r-band magnitudes ~20.3, ~21.6, and ~20.4, respectively. From preliminary photometry at the H-band source position, on the two r-band observations, we find: epoch (1) r > 19.7 (AB; against PS1) epoch (2) r = 19.8+-0.3 (AB; against PS1) We suggest that this could be the blending of the PS1 sources, only detected in the second epoch given our deeper magnitude limit with respect to the first night. Further analysis is ongoing.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 37789 SUBJECT: GRB 241013A: Fermi GBM Observation DATE: 24/10/15 15:34:38 GMT FROM: Peter Veres at University of Alabama in Huntsville P. Veres (UAH) and C. Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team: "At 00:58:34.36 UT on 13 October 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241013A (trigger 750473919/241013041). which was also detected by INTEGRAL (Gotz et al. 2024, GCN 37781). The Fermi GBM on-ground location is consistent with the INTEGRAL position. The angle from the Fermi LAT boresight is 29 degrees. The GBM light curve consists of a single emission episode with a duration (T90) of about 9 s (50-300 keV). The time-averaged spectrum from T0-6.1 to T0+3.6 s is best fit by a simple power law function with index -1.26 +/- 0.06. The event fluence (10-1000 keV) in this time interval is (1.4 +/- 0.1)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2.1 s in the 10-1000 keV band is 1 +/- 0.1 ph/s/cm^2. A power law function with an exponential high-energy cutoff fits the spectrum equally well. The power law index is -0.58 +/- 0.29 and the cutoff energy, parameterized as Epeak, is 550 +/- 200 keV. 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/"
