TITLE: GCN CIRCULAR
NUMBER: 26040
SUBJECT: GRB 191019B: Fermi GBM Final Real-time Localization
DATE: 19/10/19 23:27:25 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 23:17:13 UT on 19 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191019B (trigger 593219838.347392 / 191019970).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 216.3, Dec = -40.6 (J2000 degrees, equivalent to J2000 14h 25m, -40d 36'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 82.0 degrees.

SUBJECT: GRB 191019B: AstroSat CZTI detection
DATE: 19/10/22 09:32:48 GMT
FROM: Ramkrishna Gaikwad at IUCAA/AstroSat
R. Gaikwad, S. Gupta, 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 a GRB 191019B, which was also detected by Fermi GBM Final Real-time Localization (GCN #26040).
The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple pulses of emission with the strongest peak at 2019-10-19 23:17:13.0 UT. The measured peak count rate associated with the burst is 265 cts/s above the background in the combined data of four quadrants, with a total of 7067 cts. The local mean background count rate was 501 cts/s. Using cumulative rates, we measure a T90 of 128.3 s.
It was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range.
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.
