Abstract : Positions accurate to plus or minus 10 secs were measured with the Owens Valley interferometer for seven sources in the 1720 MHz line of OH. These included three Class I sources (W3, W49, and W51) and four Class IIa sources (W28(A1), W44, ON-3, and Glll.5+0.8). ON-3 was found to lie close to component C of the complex radio source near NGC 6857, instead of near component A (the unusual nebula K3-50). The satellite line position coincided with a main line position for the Class I sources. (Author)
