//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 27127 SUBJECT: GRB 200219B: Fermi GBM Final Real-time Localization DATE: 20/02/19 10:04:32 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 09:54:14 UT on 19 Feb 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200219B (trigger 603798859.677708 / 200219413). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 299.1, Dec = 6.7 (J2000 degrees, equivalent to J2000 19h 56m, 6d 42'), with a statistical uncertainty of 4.0 degrees. The angle from the Fermi LAT boresight is 46.0 degrees.

Ridnaia, S. Golenetskii, R. Aptekar, D. Frederiks, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, K. Hurley, on behalf of the IPN, A. Goldstein, M. S. Briggs, and C. Wilson-Hodge on behalf of the Fermi GBM team, and A. von Kienlin, X. Zhang, A. Rau, V. Savchenko, E. Bozzo, and C. Ferrigno, on behalf of the INTEGRAL SPI-ACS GRB team, report: The long-duration GRB 200219B (Fermi-GBM detection: The Fermi GBM team, GCN 27127) has been detected by Fermi (GBM trigger 603798859), Konus-Wind, INTEGRAL (SPI-ACS), so far, at about 35652 s UT (09:54:12). We have triangulated it to a preliminary, 3 sigma error arc whose coordinates are: --------------------------------------------- RA(2000), deg Dec(2000), deg --------------------------------------------- Center: 305.322 (20h 21m 17s) +17.202 (+17d 12' 07") Corners: 303.847 (20h 15m 23s) +18.943 (+18d 56' 35") 288.913 (19h 15m 39s) -24.952 (-24d 57' 07") 293.218 (19h 32m 52s) -21.998 (-21d 59' 52") 306.769 (20h 27m 05s) +15.451 (+15d 27' 04") 348.097 (23h 12m 23s) +15.820 (+15d 49' 13") 352.740 (23h 30m 58s) +17.960 (+17d 57' 35") --------------------------------------------- The error arc area is 404.4 sq. deg, and its maximum dimension is ~81 deg (the minimum one is ~5 deg). The Sun distance was ~32 deg. The LIGO/Virgo S200219ac localization (LIGO/Virgo Collaboration, GCN Circ. 27130) is inconsistent with the arc. This arc may be improved. A triangulation map is posted at http://www.ioffe.ru/LEA/GRBs/GRB200219_T35651/IPN/ The time history and spectrum will be given in forthcoming GCN Circulars.
