The on-ground calculated location, using the Fermi GBM trigger data, is RA = 104.5, Dec = 31.7 (J2000 degrees, equivalent to J2000 06h 58m, 31d 41'), with a statistical uncertainty of 3.5 degrees. The angle from the Fermi LAT boresight is 86.0 degrees.

Li (IHEP/THU), F. J. Lu, L. M. Song, M. Wu, Y. P. Xu, S. N. Zhang (IHEP), report on behalf of the Insight-HXMT team: At 2020-01-11T15:11:07.61 (T0), Insight-HXMT/HE detected GRB 200111A (trigger ID: HEB200111632) in a routine search of the data, which also triggered Fermi/GBM (GCN #26705). The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 8.474 s measured from T0-0.030 s. The 1-ms peak rate, measured from T0+5.459 s, is 1355 cnts/sec. The total counts from this burst is 2111 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB200111632_lc.jpg All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope. Insight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).

Starr, on behalf of the GRS-Odyssey GRB team, report: The long-duration GRB 200111A (The Fermi GBM team, GCN Circ. 26705; Insight-HXMT/HE detection: Xiao et al., GCN Circ. 26714) was detected by Konus-Wind, Fermi (GBM trigger 600448273), INTEGRAL (SPI-ACS), Mars-Odyssey (HEND), Insight (HXMT/HE), and Swift (BAT) at about 54668 s UT (15:11:08). The burst was outside the coded field of view of the BAT. We have triangulated it to a preliminary, 3 sigma error box whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 107.869 (07h 11m 29s) +32.551 (+32d 33' 03") Corners: 107.545 (07h 10m 11s) +34.162 (+34d 09' 42") 107.747 (07h 10m 59s) +34.483 (+34d 28' 58") 108.134 (07h 12m 32s) +30.686 (+30d 41' 10") 107.920 (07h 11m 41s) +30.214 (+30d 12' 52") --------------------------------------------- The error box area is about 2864 sq. arcmin, and its maximum dimension is 4.3 deg (the minimum one is 12.2 arcmin). The Sun distance was about 167 deg. This box may be improved. The IPN localization is consistent with, but reduces the area of, the Fermi-GBM one. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB200111_T54677/IPN/ The Konus-Wind time history and spectrum will be given in a forthcoming GCN Circular.

Circular_text TITLE: GCN CIRCULAR NUMBER: 26783 SUBJECT: GRB 200111A: AstroSat CZTI detection DATE: 20/01/16 10:01:06 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 the detection of a GRB 200111A, which was also detected by Fermi GBM Final Real-time Localization (GCN #26705) and Insight-HXMT/HE (Xiao S. et al., GCN #26714). The source was clearly detected in the 40-200 keV energy range. The light curve showed multiple peaks of emission peaking at 2020-01-11 15:11:09.0 UT. The measured peak count rate associated with the burst is 421 cts/s above the background in the combined data of four quadrants, with a total of 1251 cts. The local mean background count rate was 548 cts/s. Using cumulative rates, we measure a T90 of 8.6 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.

The burst signal was seen by all CGBM detectors. The burst light curve shows a multi-peaked structure followed by a short pulse. The emission starts at T+0.0 sec, peaks at T+6.0 sec and ends at T+6.4 sec. The T90 and T50 durations measured by the SGM data are 6.0 +- 0.5 sec and 3.9 +- 1.9 sec (40-1000 keV), respectively. The ground processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1262790473/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.
