Abstract : The Owens Valley interferometer has been used at 1665, 1667 and 1720 MHz to measure the positions of 11 OH emission sources. The typical measurement errors were plus or minus 4 sec. The 1720 MHz OH source in W3 (continuum) was found to be 40 sec away from the H2O maser source and not to coincide with any radio or infrared feature. Two OH emission sources were found in NGC 7538; one is identifiable with a very compact radio/infrared source while the other, 80 sec to the south, is as yet unidentified. The OH sources 0739-14 and Sharpless 269 also coincide with infrared sources. (Author)
