messages from heaven
Several years ago at the ASNSW star party, several of us saw a bolide break up into 3 pieces at what appeared to be not that far above our heads. I know now that it would have been miles up. Despite being not too crash hot hearing wise(deaf as a doornail), I heard such a hissing crackling sound, a bit like fireworks. Pity I did not know as much about meteorites then as I do now, as I would have been tickled pink knowing I was one of the minority who could hear the electrophonic hiss. Apparently, as the bolide breaks up it emits electromagnetic radiation which then gets retransmitted to audible sounds by nearby metallic objects.On this occasion, there were scores of telescopes in the area.The bolide shows up on one of my wide field star trail photos I was taking at the time-does not look as spectacular on the film as it should, as the lens was an 8mm f/4 circular fisheye.
