Object appearing as a star was changing light intensity while moving in the night sky.Object appearing as a star was changing light intensity from very low to very high while moving in the night sky. Interval of changing light intensity was approximately 5 secs from low to high and then 5 secs from high to low intensity. The speed was like an airplane but a little bit faster. First it was moving from south to north, and then changed direction from north to south and then it disappeared. Maybe I saw two objects because I lost it for a 15 seconds before I saw it again moving in other direction.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
