//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 28640 SUBJECT: GRB 201016B: Fermi GBM Final Real-time Localization DATE: 20/10/16 03:26:40 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 03:16:21 UT on 16 Oct 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201016B (trigger 624510986.143038 / 201016136). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 8.0, Dec = -31.8 (J2000 degrees, equivalent to J2000 00h 32m, -31d 48'), with a statistical uncertainty of 4.6 degrees. The angle from the Fermi LAT boresight is 83.0 degrees.

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 624510986 at 03:16:21 on 16 Oct. 2020 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) = 1.9+/-3.5 deg Decl.(2000.0) = -32.6+/-2.4 deg We estimate an additional systematic error of 1 deg.
