I've only heard one Electrophonic sound-- it was during a -6 SPO fireball (of course). It was really BIG. The head of the meteor was like .15 arc degrees (x.25 the arc size of the Moon) about 6 or 7 seven months ago. It was my best one ever. I just heard about the meteor that was as bright as the Sun--could this have been a Geminid? Jonathan
