LIGO/Virgo S190706ai: Coverage and upper limits from MAXI/GSC observations
Abstract
We examined MAXI/GSC all-sky X-ray images (2-20 keV) after the LVC trigger S190706ai at 2019-07-06 22:26:41.344 UTC (GCN 24998). At the trigger time of S190706ai, the high-voltage of MAXI/GSC was off, and it was turned on at T0+730 sec (+12.1 min). The first one-orbit (92 min) scan observation with GSC after the event covered 66% of the 90% credible region of the bayestar skymap from 22:39:0 to 23:58:30 UTC (T0+739 to T0+5509 sec). No significant new source was found in the region in the one-orbit scan observation. A typical 1-sigma averaged upper limit obtained in one scan observation is 20 mCrab at 2-20 keV. If you require information about X-ray flux by MAXI/GSC at specific coordinates, please contact the submitter of this circular by email.
