TITLE: GCN CIRCULAR NUMBER: 26545 SUBJECT: LIGO/Virgo S191222n: INTEGRAL was inactive at the time of the event DATE: 19/12/22 05:07:41 GMT FROM: Alexander Lutovinov at Space Research Inst.,IKI Alexander Lutovinov (IKI, Moscow), Sandro Mereghetti (INAF IASF-Milano, Italy), V. Savchenko, C. Ferrigno (ISDC/UniGE, Switzerland) J. Rodi (IAPS-Roma, Italy) A. Coleiro (APC, France) on behalf of the INTEGRAL multi-messenger collaboration: https://www.astro.unige.ch/cdci/integral-multimessenger-collaboration The INTEGRAL spacecraft has a highly elliptical orbit and the instruments are not acquiring science data during perigee passage, every 2.6 days to prevent radiation-induced damages. Unfortunately, at the time of the S191222n (2019-12-22 03:35:37, GCN26543) the spacecraft was preparing to the start the observations after the perigee passage between the orbits number 2173 and 2174 and no scientific instrument data are available between 2019-12-21T18:45:19 and 2019-12-22T10:44:07.
