Cometary, W of M9. This object is somewhat cometary in form and has a very black core or head that sharply abuts against the thick stratum of stars; from this it spreads out into a large dark area with much dark detail, filling quite a space close southwest of M9. It thus resembles a dark comet with a dense and well-defined head and diffused widening tail. The position of the head is a=17h9m57s, d=-18°20'6"― A Photographic Atlas of Selected Regions of the Milky Way, E.E. Barnard, 1927
