Details are very sketchy at this point, I heard this second hand, but I hope to talk to the witnesses soon. In the North Eugene area, three witnesses had a night time sighting of a very bright "brighter than a star" round object that moved about in the sky; witnesses observed it moving around for about 45 min. The object changed color having a multi colored effect. At one point a smaller reddish-orange orb shaped object seemed to have come out of the larger multi colored one and got closer to the witnesses, zooming and dancing around near the tree lines . . . as I say, I haven't spoken with the witnesses directly, and it's so far just a "more lights in the sky" kind of story. But I know the witnesses, and so does the person who told me about it, and I know they're not making anything up for funzies. I do find it interesting a smaller object came out of the larger one; which fits into other reports of a similar nature.
Most of all, for myself, I always wonder: if it's not ET, and not some kind of paranormal-portal visiting entity, etc. then it's ours. So if it's man made, and ours, what's that all about? What's it doing up there, what's it doing in a populated area in a smallish to medium sized city, what's it doing there behaving both covertly (cover of night) and yet overtly (colored lights, either unaware of, or not caring about, being seen.)
Another possibility: someone's remote controlled toy, but I don't see why someone would be standing out there in the cold, dark drizzle playing around with something like that, and why the two objects, though anything's possible.
Of course, the witnesses stood around for 45 min. watching the thing... so if a person is motivated enough, and an Oregonian, cool night air and some rain isn't going to bother you.
Hopefully I can get more info soon.
