H/sub 2/CO emission at 2mm is seen over a region 30' in extent which includes OMC-1 and OMC-2. The mass of this cloud, estimated from H/sub 2/CO and CO observations, is approx.7 x 10/sup 3/ D/sup 7/Alembertian/sub sun/. The velocity pattern is one of rotation, with evidence for fragmentation into two or three distinct condensations. A sharp boundary to the molecular cloud is observed at the edge of the H II region in NGC 1977. It appears likely that NGC 1977 is a condensation at the northern end of the cloud, complementary to the Orion Nebula at the southern end. (AIP)
