FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 00:28:41 UT on 6 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200506A (trigger 610417726.052718 / 200506020).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 271.7, Dec = -4.4 (J2000 degrees, equivalent to J2000 18h 06m, -4d 24'), with a statistical uncertainty of 3.9 degrees.
The angle from the Fermi LAT boresight is 87.0 degrees.

DATE: 20/05/07 14:33:06 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 weak detection of a long GRB 200506A, which was also detected by Fermi GBM (GCN #27690).
The source was clearly detected in the 40-200 keV energy range. The light curve shows multiple peaks of emission with the strongest peak at 2020-05-06 00:28:53.176 UT. The measured peak count rate associated with the burst is 143 +/- 20 cts/s above the background in the combined data of four quadrants, with a total of 1364 +/- 27 cts. The local mean background count rate was 538 +/- 1.0 cts/s. Using cumulative rates, we measure a T90 of 26.09 +/- 0.08 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.
