We report the results of a 440-day search for gravitational waves with a single 3.6 x 10/sup 6/-g aluminum 710-Hz room-temperature detector. The detector output was analyzed in real time using a microcomputer system. With the exception of a single large event, not observed by the much more sensitive antenna at Stanford University, the spectrum of events was thermal with an effective temperature T/sub e/roughly-equal6.0 K. This data implies a 90%-confidence-level upper limit of 5 x 10/sup -3/ events per day above 114 GPU for an average gravitational-wave orientation and polarization (one gravitational pulse unit = 10/sup 5/ erg cm/sup -2/Hz/sup -1/). This is the lowest limit set on the rate of gravitational radiation bursts to date.
