DATE: 19/06/19 14:27:35 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 14:16:25 UT on 19 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190619B (trigger 582646590.891184 / 190619595).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 291.1, Dec = 20.2 (J2000 degrees, equivalent to J2000 19h 24m, 20d 11'), with a statistical uncertainty of 1.8 degrees.
The angle from the Fermi LAT boresight is 93.0 degrees.

J. Burgess, B. Biltzinger, F. Kunzweiler, F. Berlato, & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
582646590 at 14:16:25 on 19 June 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) = 293.4+/-1.6 deg
Decl.(2000.0) = 14.3+/-1.8 deg
We estimate an additional systematic error of 1 deg.

SUBJECT: GRB 190619B: AstroSat CZTI detection
DATE: 19/06/26 06:22:17 GMT
FROM: Prachee Ghumatkar at IUCAA/AstroSat
P. Ghumatkar, V. Sharma, D. Bhattacharya and A. Vibhute (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 long GRB 190619B, which was also detected by Fermi GBM (GCN #24851), BALROG (Burgess J. et la., GCN #24852) and Global MASTER-Net (Lipunov V. et al., GCN #24853).
The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple pulses of emission with strongest peak at 14:16:44.5 UT. The measured peak count rate associated with the burst is 251 cts/s above the background in the combined data of four quadrants, with a total of 3318 cts. The local mean background count rate was 620 cts/s. Using cumulative rates, we measure a T90 of 38.6 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.
