OH Observations Near the Reflection Nebulae NGC 2068 and NGC 2071
Abstract
Narrow OH emission lines at 1667 MHz, apparently from a class 1 source, have been observed near the reflection nebula NUC 2071. The region contains many T Tauri stars. OH emission corresponding to the dust cloud north and east of NGC 2024 is also seen. At 1720 MHz, the dust-cloud component appears in absorption; presumably the isotropic 2.7 K cosmic background is being absorbed. Subject headings: molecules, interstellar - nebulae - radio lines
