STARE

STARE (for Survey for Transient Astronomical Radio Emission) is a distributed array of radio telescopes that aims to detect radio transients. The original STARE consisted of three small radio telescopes located at existing radio observatories (in Iowa, West Virginia, and New Hampshire), monitoring a substantial field of view surrounding the zenith (on the order of 1.4 steradian), at 611 MHz frequency. Data collected at the three was compared to discover coincident transients, much as is done with gravitational-wave detectors. Data was collected over a period of 18 months in 1998-1999, and some solar radio transients were identified. This was before the detection of fast radio bursts (FRBs) and it detected none, but it was not sensitive enough to detect the type of FRBs that were first detected.

A more recent version, STARE2, which went into operation in 2019, consists of four such telescopes covering a wider frequency-range. It aims to detect what would now be termed especially bright FRBs, presumably from Milky Way sources, and it has some detections.
