"At 3:46 am caught on home security camera an object suddenly appeared over front yard of my friends house in Warren Massachusetts hovering, jumping, pulsating, emitting beam of light then in a fraction of a second took off rapidly leaving a light trail.

This is all recorded video best watched for yourself. The home security camera picks up infrared at night so the color of the light is unknown. The size is unknown but it could be about the size of a large beach ball? This incident was all recorded on my friends home security camera and you could hear crickets so it was silent. At the end of the video you can see it take off really fast. He sent this video it to me."
