Saw a bright light, very high up, going up and down, stopping, zig zagging, and disappearing upwardI was walking in the parking lot of the Turtle Bay Resort on Oahu at the North Shore, looking at the stars. I noticed a bright light in the sky at least twice as bright as the brightest star I could see. As I was walking it seemed the light was moving, so I stopped and noticed it was moving west and was very high up. At first I thought it might be a plane, but there was no blinking, just a solid white light. The light began to turn toward the south and quickly ended up traveling eastward. The light was moving very fast for how high it was, and it began to slow down. The light dimmed a little, then proceeded to move in a zig zag motion continuing east. It slowed and zig zagged two more times. The light then grew brighter and started moving faster east, then faded quickly. It seemed that when the light grew in intensity it was descending and as it faded it was ascending.
