Strange object with flashing lights sighted over New Amsterdam, GuyanaIt was around 08:00 pm (very dark) that I looked outside and saw these strange lights in the sky. The sky was overcast since it had been raining all afternoon. I saw what appeared to be an object hovering several hundred feet up in the air in a northwesterly direction, it had what appeared to be flashing red and green lights all around it. They were flashing in a running motion sort of like neon lights do or like a series of bulbs going on and off in a very quick pattern. It was equipped with a powerful floodlight that is turned on occasionally when hovering and pointed the light up into the clouds. When I first sighted it it was motionless in the sky with just the lights flashing, I ran to grab my binoculars to get a better view and when I got back it had turned on the floodlight on by the time I got the binoculars focused the light had switched off and the craft was moving at a rather fast rate going over my house. When hovering there was no noise but as soon as it started moving I heard a noise rather like a lowflying airplane. I ran to the window on the other side of the house and watched it's flight it paused again just before the treetops would have hidden it from my view and once again turned on the floodlight. I watched it for several minutes more until it just winked out of my sight. There were low hanging clouds in the sky so it may have just risen above them but from my perspective it just seemed to vanish into thin air. I don't know if what I saw was a UFO or just a survey helicopter, since I have never seen a helicopter at night I can't say for sure but what caught my attention were the lights flashing in a pattern in what appeared to be a circle around it, I have seen airplanes at night and to my knowledge they carry signal lights that just blink. The other thing was the complete absence of noise until it started moving, won't a helicopter make a noise even when hovering and lastly the powerful floodlight that it only turned on when it had stopped in the air and pointed up into the clouds. What I would like to know is could it have been a UFO or just a helicoptor with its nightlights on. I would appreciate a response from someone on this.
