Sažetak
In November 1998 a Croatian Physical Society expedition to Mongolia was undertaken. The goal was to try to record VLF emissions and electrophonic sounds (if any) of Leonids during the anticipated Leonid storm. We obtained some instrumental recordings of very-low-frequency electromagnetic radiation (VLF) which we attribute to meteor. The detected VLF signals were coincident with the light maximum of meteors in question, and the meteors involved in these events were quite small (-5 mV and -8 mV), which implies much lower brightness limit (about -5 mV) for the VLF producing meteors then previously suggested. It is, however, not excluded that this limit depends on weather conditions. In the best recording (-8 m meteor), a 0.7 s long sequence of 8 short VLF impulses with amplitude of about 10-2 V/m, starting 0.1 s before the visual maximum of the meteor, was registered. The amount of gathered data is huge, and we are still at the analysis of it.
