H. Murakami and T. Dotani, Institute of Space and Astronautical Science; and R. Wijnands, University of St Andrews, report on the ASCA archival data analysis of the field of IGR J16318-4848 (IAUC 8063). A clear x-ray source was detected with both GIS and SIS at a position consistent with that of IGR J16318-4848, from a net exposure of 4000 s on 1994 Sept. 3.2 UT. The SIS position was determined as R.A. = 16h31m49s, Decl. = -48o49'.2 (equinox 2000.0; uncertainty about 0'.8). Murakami et al. add: "The source had a highly absorbed spectrum. If we assume a power-law continuum with a photon index fixed to 1.0, the neutral-hydrogen-absorption column density is estimated to be 4 ± 2 x 10**23 cm**-2. The source flux was about 4 x 10**-11 erg s**-1 cm**-2 in 2-10 keV when corrected for the absorption. Although the data statistics were not very high, we noticed a hint of an iron emission line at 6.4 keV."
