Circular_text	TITLE: GCN CIRCULAR NUMBER: 31052 SUBJECT: GRB 211107A: Fermi GBM Final Real-time Localization DATE: 21/11/07 20:31:01 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 20:20:40 UT on 7 Nov 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 211107A (trigger 658009245.216482 / 211107848). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 183.4, Dec = -61.2 (J2000 degrees, equivalent to J2000 12h 13m, -61d 12'), with a statistical uncertainty of 17.9 degrees. The angle from the Fermi LAT boresight is 87.0 degrees.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 31071 SUBJECT: GRB 211107A: GECAM detection DATE: 21/11/10 07:26:02 GMT FROM: Y Q Zhang at IHEP Y. Q. Zhang, S. L. Xiong, S. Xiao, C. Cai, X. Y. Zhao, Y.

Zhang (IHEP), report on behalf of GECAM team: During the commissioning phase, GECAM-B was triggered on-ground by a weak burst, GRB 211107A, at 2021-11-07T20:20:40.220 UTC (denoted as T0), which was also observed by Fermi/GBM (GCN #31052). According to the GECAM-B light curves in about 20-500 keV, this burst mainly consists of multiple pulses with a duration of 5 s. The GECAM light curve could be found here: http://twiki.ihep.ac.cn/pub/GECAM/GRBList/gecamb_lc_grd_90015640_v01.PNG GECAM location is consistent with the Fermi/GBM position within the error. Please note that all GECAM results here are preliminary. The final analysis will be published in journal papers or GECAM online catalog. Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission consists of two small satellites (GECAM-A and GECAM-B) in Low Earth Orbit (600 km, 29 deg), launched on Dec 10, 2020 (Beijing Time), which was funded by the Chinese Academy of Sciences (CAS).
