Searching for meteor ELF /VLF signatures
Résumé
For more than two centuries, credible reports about various audible sounds appearing simultaneously with visible meteors have been collected. Knowing that the sound velocity is much lower than the light velocity, it was impossible to explain such a phenomenon until some theories predicted that an electromagnetic wave vector could be the reason for such simultaneous light and sound observations. Several optical/sound/radio recording campaigns have been performed in the last decades but with no conclusive reports. The present study simply aims to examine the low frequencies electromagnetic activity during a meteor shower and to search for any interesting correlations with meteors detected by VHF forward scatter means. Preliminary results tend to show a significant correlation between certain meteors and the time-correlated corresponding ELF/VLF events. Presented at the International Meteor Conference 2009, Poreè, Croatia, 2009 September 24-27.
