We present molecular line and submillimeter dust continuum observations of the Lynds 870 cloud in the vicinity of IRAS 20231+3440. Two submillimeter cores, SMM1 and SMM2, are identified mapping the 870 micron dust continuum and ammonia emission. The total molecular mass is ~70-110 solar mass. The northern core is warmer and denser than the southern one. Molecular outflows are discovered in both cores. In the northern one a significant amount of low velocity (1.3-2.8 km/s) outflowing gas isdoi:10.1051/0004-6361:20020621 fatcat:5zvuzldcrvhuffltxpsyarmba4
