LIGO/Virgo G277583 : MAXI/GSC observations
Abstract
We examined the MAXI/GSC all-sky X-ray images (2-20 keV) obtained in the orbit and the day after the LVC trigger G277583 at 2017-03-13 22:40:09.593 UTC (GCN 20860). At the trigger time of G277583, the high-voltage of MAXI/GSC was off, and on from T0+682 sec. GSC scanned more than 74% of the whole sky in the 92-min orbit, which includes 78.3% of the 90% regions in the skyprobcc_cWB skymap. One day image covers 97.5% of the 90% regions in the skyprobcc_cWB skymap. No significant new source was found in these images. The upper limits for the X-ray flux are different depending on the part of the sky. For instance, typical 2-20 keV 1-sigma (3-sigma) upper limits obtained from the one-orbit and one-day images are 13(39) mCrab and 3(9) mCrab, respectively, If you require information of X-ray flux by MAXI/GSC at specific coordinates, please contact the submitter of this circular by email.
