Details:
I recently connected my Nasa VLF-3 receiver to the PC I use to record from my Watec 902 HU camera. I have captured the sferics generated by lightning and high voltage discharges in my area caused by power grid problems here on the Island since Hurricane Maria. I also use this setup to capture sprites and Gigantic Jet Lightning. I had no idea that my VLF receiver would pick up something from a flash in the sky that I thought was probably just a satellite glint. I know for sure that a satellite glint can not produce a VLF sound so I'm thinking that it could be something electrical in nature. Lightning will usually produce a crackling or pop sound in my receiver and that is what is heard just before the bright flash appeared. I can't say for sure that the two events were related. The faint sound generated by the flash could indicate that there is an electrical component involved, but what can it be. Auroras generate VLF sounds because of the interaction between the solar electrons and protons with the earth's magnetic field and that produces radio waves that can be picked up by a VLF receiver, so was this flash also electrical in nature?
