Witness Account

I noticed a high speed light heading east to west at dusk I initially thought it was a shooting star. The light abruptly stopped and made erratic movements above the Superstition mountains. At this point I knew that it could not be an aircraft or helicopter due to the speed and type of movement. The light would randomly go on and off as it descend out of sight on the west slope of the Superstition mountains. The entire event lasted about 1-2 minutes.
