I saw a -8 magnitude Iridium flare last night that was so bright that it seemed almost "unreal". My neighbors had never seen one so they came over and we observed it together. They were speechless. I'm surprised that more of these aren't reported as UFOs because they occur in the early evening when many people are still outside. (I know, there are early morning occurrences also.)
Since the Iridium satellites are in polar orbits, they must be quite a sight when observed closer to the poles. Anyone know? Or is their orientation such that they don't reflect the sunlight back on the Earth?
