LIGO/Virgo S200224ca: 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 S200224ca at 2020-02-24 22:22:34.406 UTC (GCN 27184). At the trigger time of S200224ca, the high-voltage of MAXI/GSC was off, and it was turned on at T0+12 sec (+0.2 min). The first one-orbit (92 min) scan observation with GSC after the event covered 100% of the 90% credible region of the bayestar skymap from 22:25:27 to 22:27:57 UTC (T0+173 to T0+323 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.
