//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 24839 SUBJECT: GRB 190615A: Fermi GBM Final Real-time Localization DATE: 19/06/15 15:28:10 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 15:16:27 UT on 15 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190615A (trigger 582304592.372344 / 190615636). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 191.4, Dec = 49.4 (J2000 degrees, equivalent to J2000 12h 45m, 49d 23'), with a statistical uncertainty of 2.3 degrees. The angle from the Fermi LAT boresight is 122.0 degrees.

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 2019-06-15T15:16:27.00 (T0), Insight-HXMT/HE detected GRB 190615A (trigger ID: HEB190615636) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #24839). The Insight-HXMT/HE light curve mainly consists of a single pulse with a duration (T90) of 16.33 s measured from T0-1.65 s. The 1-ms peak rate, measured from T0+7.80 s, is 606 cnts/sec. The total counts from this burst is 4626 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB190615636_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).
