I was lucky as my intro just after buying a scope was seeing a fireball. I had just packed up early and went out onto the porch to practise finding Constelations when a bright light decended into veiw and exploded into a shimmering ball of sparks. They were almost liquid like and brighter than anything I had seen before. It was magnificent. I can't wait to see another. (What are the odds of seeing another anyway?) I saw from my suburban home in Dandenong/Springvale area. I suppose I heard nothing emit from the fireball as the noise of traffic and general noise pollution would have smothered the sound, if any. I still do not know anyone one else who may have seen this event in Dec' 2007, but I remember it very well...
