hovering lights, like an airplane, wavering back and forth across the night sky - very slowly moving west to north at tree line levelI have been watching, on and off, for about an hour now, what looks like like the white and red flickering lights of an airplane, but which has been hovering at the tree line level in the northwestern sky all this time. It's not a star or satellite, apparently, because every few minutes it seems to randomly move about, sideways, back, up and down, in an erratic manner. But essentially it is staying in the same location in the sky. About a half hour before I noticed this, one of my dogs seemed highly agitated (unusual for her). She's settled down now. I do live near an airport, but this object has been in the air for a long time now -- essentially hovering in place.... I just went back outside to check, and initially couldn't see the lights, then realized that it had traveled further north, and was now below the tree line from where we are.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
