It's Saturday night here in Perth, Western Australia. Callers to a radio station here are going crazy. I didn't see it myself but a huge bright ball with a blue tail has just gone across the sky. Some people said it was like daylight when it crossed. It was seen for hundreds of kilometres across Perth and even in country towns. There was a big bang near one country town. Hopefully someone will go and find out what is was. Hopefully we'll get some answers soon!!
