It slowly moved northbound low and slow over rooftops.It was late at night I was in my backyard about to go to sleep. When I saw a bright light to the east heading northbound. It apeared to be a disk shape illuminated by 5 light on one side. The lights went out for about 5 seconds and then its light came back on and it exelerated like nothing on Earth. It made no sounds and it was a very breif but memorable encounter.
