LIGO/Virgo S190924h: Not observable by CALET
Abstract
At the trigger time of the compact binary merger candidate S190924h, T0 = 2019-09-24 02:18:46.847 UT (The LIGO Scientific Collaboration and Virgo Collaboration, GCN Circ. 25829), the CALET Gamma-ray Burst Monitor (CGBM) high voltages were off (from T0-1 min to T0+16 min). The CALET Calorimeter (CAL) was operating in the high energy trigger mode at the trigger time of S190924h. Using the CAL data, we have searched for gamma-ray events in the 10-100 GeV band from -60 sec to +60 sec from the GW trigger time and found no candidates. There is no significant overlap with the high probability localization region. The CAL FOV was centered at RA=273.4 deg, Dec=40.2 deg at T0.
