The Fermi GBM team reports the detection of a likely LONG GRB
At 01:22:55 UT on 7 Feb 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200207A (trigger 602731380.598244 / 200207058).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 244.1, Dec = -48.3 (J2000 degrees, equivalent to J2000 16h 16m, -48d 17'), with a statistical uncertainty of 3.2 degrees.
The angle from the Fermi LAT boresight is 117.0 degrees.

SUBJECT: GRB 200207A: AstroSat CZTI detection
DATE: 20/02/10 10:08:46 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 a weak detection of long GRB 200207A, which was also detected by Fermi GBM Final Real-time Localization (GCN #27005) and Global MASTER-Net (Lipunov V. et al., GCN #27009).
The source was clearly detected in the 40-200 keV energy range. The light curve showed a single peak of emission peaking at 2020-02-07 01:22:55.0 UT. The measured peak count rate associated with the burst is 146 +/- 23.0 cts/s above the background in the combined data of four quadrants, with a total of 641 +/- 14.9 cts. The local mean background count rate was 534 +/- 1.1 cts/s. Using cumulative rates, we measure a T90 of 9.2 +/- 0.04 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.
