UFO Sighting in Arecibo, Arecibo on April 16th 2015 – I went outside to take out trash when we noticed the lights hovering

My daughter and her boyfriend were outside talking so I decided to take out the trash. As I was coming back inside I noticed an object with pulsating lights in the night sky. It remained stationary with no sound. I went inside to get my cell and took pictures and video. It seemed to appear and fade and then come back. It was pretty far so the quality of pictures and video is not too goid. Lights changed color from red orange to bluish. Lights were pulsating. We watched it for about 2 minutes and then it just dissapeared. When I go outside at night I love to look at the stars and this night it was something I had never seen before. Very different from another sighting I experienced back in 1985 at a Small Inn called "Parador Villa Antonio" in Rincon, Puerto Rico.
