VLF detection of fireballs

The results from 80 hours of simultaneous visual/video and VLF recordings made during the Lyrids, Perseids, Orionids, Leonids and Geminids are presented. All meteor magnitudes from −11 to +4 have been sampled at least once during these observations. The only positive VLF fireball detection was made at 19:57:32 UT on August 11, 1993 from the South of France. We present a Fourier transform analysis of this event and we also derive a lower limit to the electrical field strength produced by the fireball at the antenna. Our present observations suggest a lower limit of Mv ≈ −10 ± 1 for a fireball to produce a VLF signal.
