Real-time analysis of a gravitational wave detector signal yields a condensed summary of the antenna history in the system described here. Optimal filtering is performed on the antenna signal and impulses above a preset threshold are recorded in detail using a microprocessor system. Histograms are made of the optimal filter output and of the long-term Brownian motion of the antenna. A permanent record of the large events is made on a chart recorder and a teletype, giving the details of the event pulse shape as well as numerical values of the energy and the time of the event. This provides a record of any large events in a form that can be easily correlated with data from other experiments. No events were recorded above 113 gravitational pulse units (10/sup 5/ erg/cm/sup 2/ Hz) at 710 Hz in the 39.5 days of data presented here.
