R. ; Brown, R. L. Abstract Emission from OH and H2O masers has been detected in the direction of the Monoceros-R2 molecular cloud. Only 1612- and 1665-MHz masers are observed, and from the emission characteristics of the sources, we conclude that they arise in different locations; we are observing both type I and type IIb OH masers in this region. Two velocity components of the 1665-MHz source are highly linearly polarized (about 100%). This result allows us to determine limits on the magnetic-field strength in the emission region, and to estimate its orientation. The relation of the maser emission to the embedded H II region and to the infrared sources in this cloud is discussed. The Mon-R2 region is similar to the Orion nebula complex, and appears to represent a somewhat earlier stage of star formation.
