DESCRIPTION:For more than 200 years large meteors called fireballs enterin
 g the atmosphere have been observed to produce audible sounds simultaneous
 ly with the optical flash. Since sound waves travel much slower that visib
 le light\, the only explanation was that electromagnetic waves produced by
  the meteors induce a vibration in a transducer close to the observer\, pr
 oducing an audible sound\, known as electrophonics. VLF detections were pa
 rtly successful in the past\, but no ELF observations have shown direct an
 d reliable relation to meteors despite being theoretically predicted. A ne
 w system has been designed and set at the world's largest ground-based Sch
 umann antenna to detect ELF signals. Observations were started in December
  2015 and new data is being processed\, showing statistical correlation be
 tween number of meteors and detected signals.
