TITLE: GCN CIRCULAR NUMBER: 20867 SUBJECT: LIGO/Virgo G277583: INTEGRAL was inactive at the time of the event DATE: 17/03/14 13:15:44 GMT FROM: Volodymyr Savchenko at APC,Paris V. Savchenko (ISDC, University of Geneva, CH) on behalf of the INTEGRAL group: S. Mereghetti (IASF-Milano, Italy), C. Ferrigno ((ISDC, University of Geneva, CH), E. Kuulkers (ESTEC/ESA, The Netherlands), A. Bazzano (IAPS-Roma, Italy), E. Bozzo, T. J.-L. Courvoisier (ISDC, University of Geneva, CH) S. Brandt (DTU - Denmark) R. Diehl (MPE-Garching, Germany) L.

Ubertini (IAPS-Roma, Italy) The INTEGRAL spacecraft has a highly elliptical orbit and the instruments are switched off around the perigee passage, every 2.6 days, to prevent radiation-induced damages. Unfortunately, at the time of the LIGO/Virgo trigger G211117 (2017-03-13 22:40:09.59 UTC) the spacecraft was preparing to the perigee passage between the orbits number 1792 and 1793, and no scientific instrument data are available after 2017-03-13T22:25:25.
