The Draco nebula, the faint reflection nebulosity LBN 406/412/415 (Lynds 1965) at 1≈91°, b≈38°, z≥500 pc (Goerigk and Mebold, 1986), contains delicate filaments at its low-1, low-b (SW) boundary (Goerigk et al. 1983, Mebold et al. 1985). The density in the boundary is characterized by the presence of molecules like CO and H2CO (Mebold et al. 1985) and NH3 (Mebold et al. 1987). Johnson (1986) found an excess of unidentified IRAS point sources in the area of the Draco nebula, a large fraction of which is located close to the SW boundary.
