Small yellowish blinking light, no sound, odd movement over my house

It was early darkness when my dog started barking loudly inside my house.  I assumed it was an animal (deer, rabbit, etc) that she could sense outside (I had no outside lights on when she barked).  I flipped on the outside lights and saw nothing, but when I looked up into the dark starless sky I saw a small, blinking, yellowish light traveling in an odd pattern,like it was randomly surveying the ground.  Elevation was about 2,000 ft. It made no sound at all as I went outside to view and listen. It flew no traffic pattern consistent with the state airport or the small local airport. Rather, it made a smooth turn to the east from the southwest, and continued out toward what would be the Atlantic ocean nearby. The blinking was orderly and not random and the speed was rather slower than regular aircraft.  I lost sight of it as it proceeded east to the ocean.  Dogs are able to pick up odd vibrations and subtle sounds much more than humans and I do pay attention t! o what my dogs 'see' and hear.
