TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2866 SUBJECT: GRB 041219 - A long GRB detected by INTEGRAL DATE: 04/12/19 03:31:58 GMT FROM: Sandro Mereghetti at IASF/CNR D. Gotz, S. Mereghetti (IASF, Milano), S.Shaw, M. Beck (ISDC, Versoix), J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A very long (about 9 minutes ) and bright GRB has been detected with the INTEGRAL Burst Alert System (IBAS) on December 19 at 01:43 UT. The GRB has been detected with IBIS/ISGRI in the 15-200 keV band (IBAS Alert # 2073). Its coordinates (J2000) are: RA: 6.1075 [degrees] DEC: +62.8349 [degrees] with an uncertainty of 2 arcmin (90% c.l. radius) The brightest part of the burst saturated the available telemetry. Therefore at the moment we can only estimate a lower limit to the peak flux in the 20-200 keV range. This is about 12 photons/cmsq/s (1E-6 erg/cmsq/s) (1 s integration time).
