Extremely Bright Flash Of light at nightWhile living in Hervey Bay Queensland, Australia at approximately 11:30 pm during late November of 2006, I went outside to the back yard of our house to have a cigarette. As I was standing there a bright flash lit up the night sky. The flash lasted only for two or three seconds. It was a clear night there were no clouds in the sky, this was not lightning. It was as if suddenly it was daytime for a few seconds and then night time again. The source of the flash seemed to come from behind me and my house which would have been to the north west. At the time of the flash I noticed my shadow pointing away from me and this is how I determined the direction of the source of the light. I checked the skies in all directions after the flash and saw nothing. I have never experienced such a bright flash of light before.((NUFORC Note: Source of report indicates that the date of the incident is approximate. PD))
