  Here we report on a two year continuous survey to examine possible VLF
signals associated with meteors brighter than magnitude -5. Our survey allowed
both calibrated temporal and spatial correlations between VLF signals and
fireball lightcurves. We used continuous observations from the Atmospheric
Weather Electromagnetic System for Observation Modeling and Education (AWESOME)
VLF receiver system (Cohen et al., 2010) deployed at the Elginfield Observatory
near London, Ontario, Canada (43N, 81W) to monitor VLF radio signals and
correlate with all-sky video recordings of fireballs. This survey from May 2017
to March 2019 was cued using fireballs detected by the Southern Ontario Meteor
Network (Brown et al., 2010; Weryk et al., 2007). The GPS conditioned timing of
the AWESOME system was continuously synchronized with video recordings directly
in the video stream to ensure sub-frame VLF-optical time calibration. The
AWESOME system has two orthogonal VLF antennas which permits directional
calculation of incoming VLF signals, which were compared to the apparent
optically measured locations of simultaneously detected fireballs. VLF events
potentially linked to fireballs were checked against the National Lightning
Detection Network (NLDN) database to remove false positive association with
lightning. During the two year survey interval, over 80 bright meteors
(apparent magnitude brighter than -5, brightest recorded event -7.8) were
detected and compared to VLF signals detected by the AWESOME system. No
definitive evidence was found for VLF emission from meteors up to a limiting
magnitude of -7.8.
