Abstract
A full-time dedicated SETI progam has been in operation at Ohio State University since 1973. A 50-channel narrowband filter bank is in use near the 21 cm. hydrogen-line. All data is processed in real time and permanently recorded. A large portion of the northern sky has been surveyed and analyzed for large-scale structure. The only obvious non-random structure is caused by isolated narrowband pulses, which are anti-correlated with galactic latitude, and congregate in two specific areas. The origin of these pulses is unknown, although they may be partially due to instrumental effects.
