UFO - Melbourne- 1st Jan 2012 - Looks organic???

What's interesting with this one ... we we're out an about on New Year's Eve in NSW ... and we'd all observed an identical 'orb' in the sky. We'd all dismissed it as nothing more than a satellite. A very face moving satellite mind you ...... until it suddenly disappeared! Since we have eye witnessed a similar object ... this has caught my attention as 'interesting'
