Lien (UMBC/GSFC) report on behalf\nof a larger collaboration:\n\nWe re-observed the field of SSS17a (Coulter et al., LVC GCN 21529) with\nthe Chandra X-ray Observatory (PI: E. Troja) on 2017-09-01\n(~15 days after the LVC trigger) for a total exposure of 47 ks.\n\nThe X-ray source reported in Troja et al. (LVC GCN 21765) is still\ndetected.\nAt the position of the optical/IR transient we measure ~17 net counts.\nBy describing the spectrum with an absorbed power-law we estimate a flux\nof approximately 4.5E-15 erg/cm2/s (0.5-8.0 keV).\n\nWe thank Belinda Wilkes and the entire Chandra team for approving and\nscheduling these observations.",
