Fuse and IUE observations of Sk-69 246, a WN 6 star to the north of 30 Dor, reveal the existence of LMC interstellar gas in at least 3 velocity components. In one of these components Fuse spectra show strong absorption by molecular hydrogen with a column density of (H. We investigate the physical conditions in this cloud, which is probably located near the Hii region surrounding Sk-69 246. HD and CO with column densities of and 13.0, respectively, are detected. The N(CO)-to-N(H2) ratio is consistent with values found in the Galaxy. From the population of the rotational levels of H2 we derive a gas temperature of 72 K and a radiation field erg s-1 cm-3 at 1000 Å. The fractional abundance is rather high for an .
