Circular_text	TITLE: GCN CIRCULAR NUMBER: 26256 SUBJECT: GRB 191118A: Fermi GBM Final Real-time Localization DATE: 19/11/18 22:19:53 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 22:12:01 UT on 18 Nov 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191118A (trigger 595807926.820754 / 191118925). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 214.0, Dec = -48.4 (J2000 degrees, equivalent to J2000 14h 16m, -48d 23'), with a statistical uncertainty of 2.2 degrees. The angle from the Fermi LAT boresight is 105.0 degrees.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 26257 SUBJECT: GRB 191118A: BALROG localization (Fermi Trigger 595807926 / GRB 191118925) DATE: 19/11/18 22:33:53 GMT FROM: Jochen Greiner at MPE,Garching F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 595807926 at 22:12:01 on 18 Nov. 2019 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60). The best-fit position (1 sigma statistical errors) is: RA(2000.0) = 218.5+/-6.0 deg Decl.(2000.0) = -49.3+/-3.3 deg We estimate an additional systematic error of 1 deg.

Li (IHEP/THU), F. J. Lu, L. M. Song, M. Wu, Y. P. Xu, S. N. Zhang (IHEP), report on behalf of the Insight-HXMT team: At 2019-11-18T22:12:01.82 (T0), Insight-HXMT/HE detected GRB 191118A (trigger ID: HEB191118925) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #26256). The Insight-HXMT/HE light curve mainly consists of a single pulse with a duration (T90) of 15.71 s measured from T0+0.12 s. The 1-ms peak rate, measured from T0+7.85 s, is 928 cnts/sec. The total counts from this burst is 7570 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB191118925_lc.jpg All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope. Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
