Circular_text TITLE: GCN CIRCULAR NUMBER: 22146 SUBJECT: IPN Triangulation of GRB 171119A (long) DATE: 17/11/22 09:41:43 GMT FROM: Dmitry Svinkin at Ioffe Institute K. Hurley, on behalf of the IPN, I. G. Mitrofanov, D. Golovin, M. L. Litvak, and A. B. Sanin, on behalf of the HEND-Odyssey GRB team, D. Svinkin, S. Golenetskii, R. Aptekar, D. Frederiks, A.

Briggs, C. Meegan, V. Pelassa, and A. Goldstein, on behalf of the Fermi GBM team, and W. Boynton, C. Fellows, K. Harshman, H. Enos, and R. Starr, on behalf of the GRS-Odyssey GRB team, report: The long-duration GRB 171119A was detected by Fermi (GBM trigger 532828112), Konus-Wind, INTEGRAL (SPI-ACS), and Mars-Odyssey (HEND) at about 85707 s UT (23:48:27). We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 135.318 (09h 01m 16s) -50.281 (-50d 16' 53") Corners: 136.349 (09h 05m 24s) -52.250 (-52d 14' 59") 134.356 (08h 57m 26s) -48.624 (-48d 37' 25") 134.404 (08h 57m 37s) -48.273 (-48d 16' 21") 136.374 (09h 05m 30s) -51.905 (-51d 54' 19") --------------------------------------------- The error box area is 1893 sq. arcmin, and its maximum dimension is 4.17 deg (the minimum one is 8.2 arcmin). The Sun distance was 80 deg. This box may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB171119_T85705/IPN/ The time history and spectrum will be given in forthcoming GCN Circulars.

Circular_text TITLE: GCN CIRCULAR NUMBER: 22147 SUBJECT: Konus-Wind observation of GRB 171119A DATE: 17/11/22 10:09:22 GMT FROM: Dmitry Frederiks at Ioffe Institute D. Frederiks, S. Golenetskii, R.Aptekar, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lysenko, A. Kozlova, and T. Cline, on behalf of the Konus-Wind team, report: The long GRB 171119A (IPN Triangulation: Hurley et al., GCN 22146) triggered Konus-Wind at T0=85705.835 s UT (23:48:25.835) The burst light curve shows a multi-peaked structure with a total duration of ~33 s. The emission is seen up to ~10 MeV. As observed by Konus-Wind, the burst had a fluence of (4.6 ± 0.5)x10^-5 erg/cm2 and a 64-ms peak energy flux, measured from T0+5.248, of (1.7 ± 0.2)x10^-5 erg/cm2 (both in the 20 keV - 10 MeV energy range). The time-integrated spectrum (measured from T0 to T0+39.936 s) is best fit in the 20 keV - 15 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -0.84 (-0.09,+0.09), the high energy photon index beta = -2.71 (-0.69,+0.27), the peak energy Ep = 232 (-19,+22) keV, chi2 = 94/97 dof. The spectrum near the peak count rate (measured from T0+0.256 s to T0+5.632 s) is best fit in the 20 keV - 15 MeV range by the GRB (Band) function with the following model parameters: the low-energy photon index alpha = -0.55 (-0.12,+0.16), the high energy photon index beta = -2.33 (-0.22,+0.17), the peak energy Ep = 255 (-33,+32) keV, chi2 = 122/97 dof. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB171119_T85705/ All the quoted errors are estimated at the 90% confidence level. All the presented results are preliminary.

Circular_text TITLE: GCN CIRCULAR NUMBER: 22163 SUBJECT: GRB 171119A: AstroSat CZTI detection DATE: 17/11/24 16:11:56 GMT FROM: Vidushi Sharma at IUCAA V. Sharma and D. Bhattacharya (IUCAA), V. Bhalerao (IIT-B), A. R. Rao (TIFR) and S. Vadawale (PRL) report on behalf of the Astrosat CZTI collaboration: Analysis of Astrosat CZTI data showed the detection of GRB 171119A, which was also detected by IPN Triangulation (Hurley K. et al., GCN 22146) and Konus-Wind observation (Frederiks D. et al., GCN 22147). The source was clearly detected in the 40-200 keV energy range. The light curve of the CZT detector shows a multiple peak of emission at 23:48:33 UT. The measured peak count rate is 611.9 cts/s above the background in combined data of four quadrants, with a total of 2704 cts. The local mean background count rate was 263.1 cts/s. Using cumulative rates, we measure a T90 of 10.3 s. It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The Veto light curve shows a strong peak coincident with the peak in the CZT detector. CZTI GRB detections are reported regularly on the payload site at http://astrosat.iucaa.in/czti/?q=grb. CZTI is built by a TIFR-led consortium of institutes across India, including VSSC, ISAC, IUCAA, SAC and PRL. The Indian Space Research Organisation funded, managed and facilitated the project.
