SUBJECT: GRB 200510A: Fermi GBM Final Real-time Localization
DATE: 20/05/10 10:51:33 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 10:41:16 UT on 10 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200510A (trigger 610800081.958626 / 200510445).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 155.1, Dec = -1.9 (J2000 degrees, equivalent to J2000 10h 20m, -1d 53'), with a statistical uncertainty of 1.5 degrees.
The angle from the Fermi LAT boresight is 67.0 degrees.

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
610800081 at 10:41:16 on 10 May 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) = 155.2+/-2.1 deg
Decl.(2000.0) = -1.9+/-2.9 deg
We estimate an additional systematic error of 2 deg.

SUBJECT: GRB 200510A: AstroSat CZTI detection
DATE: 20/05/11 19:50:59 GMT
FROM: Soumya Gupta at IUCAA/ASTROSAT
S. Gupta, V. Sharma and D. Bhattacharya (IUCAA), V. Bhalerao (IIT-B), A. R. Rao (IUCAA/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 200510A, which was also detected by Fermi GBM (GCN #27711) and BALROG (Kunzweiler
F. et al.,GCN #27712).
The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple peak of emission with the strongest peak at 2020-05-10 10:41:16.542 UT. The measured peak count rate associated with the burst is 310 +/- 27 cts/s above the background in the combined data of four quadrants, with a total of 967 +/- 10 cts. The local mean background count rate was 496 +/- 1.0 cts/s. Using cumulative rates, we measure a T90 of 9.29 +/- 0.005 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.
