Using SERENDIP processor. Have searched declinations +8 to -36. By 1989 it had searched declinations +62 to -22 and was continuing to -36. The receiver was tuned in to hydrogen's rest frequency relative to the Galactic Center (as a function of direction). Program ended when OSU sold observatory site to golf course developer. It was the longest running sky-survey with improving capabilities over time. This survey of the entire sky between the telescope declination limits of +63 (degrees) and -36 (degrees) is continuous in direction, making no assumptions as to where an extraterrestrial transmitter might be located in space. Out to a distance of 1000 light years, there are an average of three F-, G-, and K-type stars in the beam of the telescope at all times. The telescope is a meridian transit instrument, with half-power beamwidths at 21 cm of 8 arcmin in right ascension and 40 arcmin in declination. The system temperature is approximately 100(degrees) K, and an integration time of 10 sec was used. No confirmed narrowband extraterrestrial signals have been found.
