Several lights that moved slowly in same area for 45 minutes, flashing colors, disappearing, reappearing, splitting in two.

Bright lights that would be best described as "moving stars" appeared from 5 to 20 degrees above the horizon and would dim and go out, only to return again. At maximum, there were 3 at a time. It was difficult to tell how many craft there were, because they would disappear and reappear so we were unable to discern whether they were same craft or new craft. They hovered and moved slowly in the same area for approximately 45 minutes beginning at dusk. Several times, one of the lights would become very bright and flash brilliant colors in quick pulses, in a random rhythm (unlike the steady rhythm of flashing lights on a plane). At one point when one became very bright and flashed colors for a few minutes, it then dimmed slightly and split into two separate white lights that moved slowly in separate trajectories then each dimmed out, to the point of being completely extinguished. Once it became completely dark, the activity subsided to the point where ! there was only one light visible consistently, though it did dim, fully extinguish, and come back again. At one point we also observed a faint white orb that seemed to come out of one of the brighter lights, move away, and then dim to the point of being completely extinguished.
