SUBJECT: GRB 190610B: Fermi GBM Final Real-time Localization
DATE: 19/06/10 18:11:12 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 17:59:49 UT on 10 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190610B (trigger 581882394.908204 / 190610750).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 327.4, Dec = 42.4 (J2000 degrees, equivalent to J2000 21h 49m, 42d 23'), with a statistical uncertainty of 1.2 degrees.
The angle from the Fermi LAT boresight is 19.0 degrees.

FROM: Jochen Greiner at MPE,Garching
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
581882394 at 17:59:49 on 10 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) = 327.4+/-1.7 deg
Decl.(2000.0) = 45.4+/-0.6 deg
We estimate an additional systematic error of 2 deg.

[GCN OPS NOTE(10jun19): Per author's request, the GRB name in the Subject
was changed from "GRB 190610A" to "GRB 190610B".]

SUBJECT: GRB 190610B: AstroSat CZTI detection
DATE: 19/06/12 06:19:37 GMT
FROM: Prachee Ghumatkar at IUCAA/AstroSat
P. Ghumatkar, V. Sharma, D. Bhattacharya, T. Khanam 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 190610B, which was also detected by Fermi GBM (GCN #24777), BALROG (Burgess J. et al., GCN # 24778) and Global MASTER-Net (Lipunov V. et al., GCN # 24779).
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 18:00:05.5 UT. The measured peak count rate associated with the burst is 346 cts/s above the background in the combined data of four quadrants, with a total of 1899 cts. The local mean background count rate was 548 cts/s. Using cumulative rates, we measure a T90 of 13.5 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.
