Query: Detection of Radio Emission from Fireballs   We present the findings from the Prototype All-Sky Imager (PASI), a backend
correlator of the first station of the Long Wavelength Array (LWA1), which has
recorded over 11,000 hours of all-sky images at frequencies between 25 and 75
MHz. In a search of this data for radio transients, we have found 49 long (10s
of seconds) duration transients. Ten of these transients correlate both
spatially and temporally with large meteors (fireballs), and their signatures
suggest that fireballs emit a previously undiscovered low frequency,
non-thermal pulse. This emission provides a new probe into the physics of
meteors and identifies a new form of naturally occurring radio transient
foreground.
