At approximately 8:40 PM, two of us witnessed two large, orange orbs of light moving across the sky. Because we were on a mountain, visibility was high, and every passing airplane made sound; this did not. The lights were much bigger and brighter than an airplane and it was visible for 2-3 minutes as it passed over the next town. Instead of disappearing over the the horizon, it went up toward the sky until it disappeared. 2 minutes later, it reappeared in the same area it had come from, lower and brighter than before. It floated stationary for 5 or 10 seconds. Then it dimmed out and shrunk to nothing, fully disappearing.
