UFO on the night of the Paterson Falls View Festival

I dont recall the exact date but I remember it was on the Night of the Falls View Festival in Paterson and it had to be between 1975-78. My mother and I were walking to the Falls along with dozens of other people and directly above us we witnessed a hovering  object, It appeared round from our view with circling lights on the bottom. It s hard to say how high it was but my mother and I and a crowd of people including a police officer who shined his spotlight on the object stood there spellbound for at least 2 full minutes until it slowly drifted off to the side and out of sight.
 There is an entry for a sighting in Paterson in 1980 and it sounds very similar,  I have always wondered if anyone still remembers that night. My mom and I have never forgotten that night nor have we ever seen another sighting.
Witness indicates that the date of the event is approximate.  PD
