DATE: 20/01/12 12:44:39 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 12:36:31 UT on 12 Jan 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200112A (trigger 600525396.101104 / 200112525).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 150.1, Dec = 64.4 (J2000 degrees, equivalent to J2000 10h 00m, 64d 24'), with a statistical uncertainty of 2.0 degrees.
The angle from the Fermi LAT boresight is 118.0 degrees.

B. Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
600525396 at 12:36:31 on 12 Jan. 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) = 147.7+/-6.8 deg
Decl.(2000.0) = 66.5+/-1.4 deg
We estimate an additional systematic error of 2 deg.

SUBJECT: GRB 200112A: AstroSat CZTI detection
DATE: 20/01/13 12:11:04 GMT
FROM: Ramkrishna Gaikwad at IUCAA/AstroSat
R. Gaikwad, V. Sharma, A. Vibhute 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 the detection of a GRB 200112A, which was also detected by Fermi GBM Final Real-time Localization (GCN #26711) and BALROG localization (Biltzinger B. et al., GCN #26713).
The source was clearly detected in the 40-200 keV energy range. The light curve showed a single peak of emission peaking at 2020-01-12 12:36:31.0 UT. The measured peak count rate associated with the burst is 688 cts/s above the background in the combined data of four quadrants, with a total of 2590 cts. The local mean background count rate was 536 cts/s. Using cumulative rates, we measure a T90 of 11.9 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.
