Optical observations of the dark cloud Kh 15 resulted in distance and extinction estimates. An extinction layer appears in the direction of the cloud at distance modulus 6m7, i.e. it is located at a distance of 220±40 pc, with an average extinction of AV = 0m35. CO observations revealed a cometary shaped small cloud with a dense 13CO core of 12 Msun with peak column density of N(13CO) ≍ 4×1015cm-2. The total gas mass in Kh 15 from 13CO measurements is 27 Msun. The small, non-starforming dark cloud seems to be connected to a large FIR shell. Its velocity, and density structure reflects a past shock passage, possibly due to the same effect which formed the shell.
