“…Our previous analysis (Charman et al 1970) had failed to yield any convincing evidence for large radio pulses from objects other than the Sun. The Sun, however, produces a copious number of pulses in the VHF band, and hence in general our previous searches were limited to the quieter nighttime hours.…”

“…In our first experiments to search for coincident radio pulses at widely spaced stations (Charman et al 1970) the antennas were essentially all-sky viewing. In later experiments directional antennas were added, originally directed toward the galactic center (Charman et al 1971) and later toward the Crab Nebula (Meikle et al 1972).…”

“…We describe here a large solid-angle, low-gain system for detecting transient astronomical radio emission at 611 MHz on time scales of a few minutes or less. Similar in spirit to the work of Charman et al (1970) and Mandolesi et al (1977), STARE updates previous efforts through the use of modern technology. The wide availability of fast computers and other hardware permits the collection of data in digital form.…”

We have constructed and operated the Survey for Transient Astronomical Radio Emission (STARE) to detect transient astronomical radio emission at 611 MHz originating from the sky over the northeastern United States. The system is sensitive to transient events on timescales of 0.125 s to a few minutes, with a typical zenith flux density detection threshold of approximately 27 kJy. During 18 months of around-the-clock observing with three geographically separated instruments, we detected a total of 4,318,486 radio bursts. 99.9% of these events were rejected as locally generated interference, determined by requiring the simultaneous observation of an event at all three sites for it to be identified as having an astronomical origin. The remaining 3,898 events have been found to be associated with 99 solar radio bursts. These results demonstrate the remarkably effective RFI rejection achieved by a coincidence technique using precision timing (such as GPS clocks) at geographically separated sites. The non-detection of extra-solar bursting or flaring radio sources has improved the flux density sensitivity and timescale sensitivity limits set by several similar experiments in the 1970s. We discuss the consequences of these limits for the immediate solar neighborhood and the discovery of previously unknown classes of sources. We also discuss other possible uses for the large collection of 611 MHz monitoring data assembled by STARE.Comment: 24 pages, 6 figures; to appear in PAS

“…Possibility (iii) is attractive, but will require theoretical models which do not exist today; possibility (iv) will require this and more --either we live in an exceptionally active epoch, or our present cosmological understanding is wildly defective. (Note that the epoch must be peculiarly active in gravitational waves alone: there is no evidence for coincident radio bursts [Partridge (1971), Charman et al (1970)] or neutrino bursts [Bahcall and Davis (1971)]. …”
