CCD images, surface polarimetry, and long-slit spectrograms of a hitherto unknown cometary reflection nebula associated with a dense dust cloud are presented. A bright, compact Herbig-Haro object is embedded in its brightest part. The highly reddened illuminating star of about 3-5 solar masses is located near the apex of the nebula; it emits a collimated bipolar high-velocity flow whose blueshifted component feeds the Herbig-Haro object. The redshifted component can be traced toward the interior of the dark cloud, where the density exceeds 100,000/cu cm. 20 references.
