No pic??? Did it really happen?? lol
Seriously though could have been anything....i wouldnt put money on it being an alien craft, probably coincidence with the chopper.
It could have been a toy, a chopper, a plane, a military craft, a satellite, a blimp, a whole multitude of things. No picture means theres very little chance anyone can identify what it was for sure so yea...its a UFO lol.
You provided little content about the speed, height, lenght of time between chopper and lights....so little info
