Orange orb saw by three people that suddenly vanished away from us.

Myself, my father, and my grandfather were standing on the balcony at prince resort on the 16th floor. My father saw the object first. He got my and my grandfather's attention and then we looked.  It was a glowing bright orange orb probably out a few miles past the pier.  It was over the ocean at least 500 feet above it. We were all asking each other what it was.  It slowly moved to the left and then looked like it was slowly moving toward us.  At that point we ruled a flare out because it did not travel as such. After it slightly moved towards us it took a move away and then vanished with no trace or trail. Almost like a teleport.  I have or had never seen anything like this so to me it can only be a UFO or a government test.  Upon research of sightings on this area the next day, I concluded that most of the reports I saw were of the same object or similar multiple objects. I would just like to know for peace of mind. Could not get a photo because it happened so fast and did not want to stop watching it.
