TITLE: GCN CIRCULAR NUMBER: 25390 SUBJECT: LIGO/Virgo S190814bv: Not observable by CALET DATE: 19/08/18 03:55:21 GMT FROM: Yuta Kawakubo at Louisiana State U./CALET S. Ozawa (Waseda U) A. Yoshida, T. Sakamoto, V. Pal'shin, S. Sugita (AGU), Y. Kawakubo (LSU), K. Yamaoka (Nagoya U), S. Nakahira (RIKEN), Y. Asaoka, S. Torii (Waseda U), Y. Shimizu, T. Tamura (Kanagawa U), N. Cannady (GSFC/UMBC), M. L. Cherry (LSU), S. Ricciarini (U of Florence), P. S. Marrocchesi (U of Siena), and the CALET collaboration: At the trigger time of the compact binary merger candidate S190814bv, T0 = 2019-08-14 21:10:39.013 UT (The LIGO Scientific Collaboration and Virgo Collaboration, GCN Circ. 25324, 25333), the CALET Gamma-ray Burst Monitor (CGBM) high voltages were off (from T0-10 min to T0+7 min). The CALET Calorimeter (CAL) was operating in the high energy trigger mode at the trigger time of S190814bv, but the CAL FOV does not have any overlap with LVC probability significance map. The CAL FOV was centered at RA= 181.3 deg, DEC= 49.5 deg at T0.
