A molecular outflow has been discovered in the northern part of L673, a nearby molecular cloud, in CO and (C-13)O observations with the University of Cologne 3 m telescope on the Gornergrat. The angular extent of this outflow, 10 arcmin x 15 arcmin, is among the largest so far discovered, making it a good candidate for detailed study. The physical characteristics of the outflow are not unusual, but the physical size, 1.3 pc x 0.9 pc, is greater than that of most outflows presently known. There is a small nebulosity, RNO109, on the POSS red print about 2 arcmin from the apparent center of the outflow and coincident with an IRAS point source with colors appropriate for an embedded star; it is the most likely candidate for the source of the outflow.
