After several months of operation, calibration, and shakedown, the National Radio Astronomy Observatory has dedicated its 140‐ft‐diameter, S13‐million radiotelescope. Operating to an accuracy better than 10 seconds of arc (a dime at 400 yards), the newly completed instrument has been called the largest antenna of such precision in the world. Associated Universities, which also operates Brookhaven National Laboratory, operates the Green Bank, West Virginia observatory under contract to the National Science Foundation.
