Circular_text TITLE: GCN CIRCULAR NUMBER: 25319 SUBJECT: GRB 190814A: Fermi GBM Final Real-time Localization DATE: 19/08/14 20:15:37 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 20:05:22 UT on 14 Aug 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190814A (trigger 587505927.990858 / 190814837). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 60.4, Dec = -60.3 (J2000 degrees, equivalent to J2000 04h 01m, -60d 17'), with a statistical uncertainty of 30.2 degrees. The angle from the Fermi LAT boresight is 62.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 25363 SUBJECT: GRB 190814A: Insight-HXMT/HE detection DATE: 19/08/16 13:00:28 GMT FROM: Ce Cai at IHEP C. Cai, Q. Luo, S. Xiao, Q. B. Yi, Y. G. Zheng, Y. Huang, C. K. Li, X. B. Li, G. Li, J. Y. Liao, S. L. Xiong, C. Z. Liu, X. F. Li, Z. W. Li, Z. Chang, A. M. Zhang, Y. F. Zhang, X. F. Lu, C. L. Zou (IHEP), Y. J. Jin, Z. Zhang (THU), T. P. 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 2019-08-14T20:05:21.00 (T0), Insight-HXMT/HE detected GRB 190814A (trigger ID: HEB190814837) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #25319). The Insight-HXMT/HE light curve mainly consists of a single pulse with a duration (T90) of 5.08 s measured from T0-0.64 s. The 1-ms peak rate, measured from T0+0.16 s, is 718 cnts/sec. The total counts from this burst is 2077 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB190814837_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).
