Object was Pretending to be a Star

Went outside to take my dog for a walk. It was a clear morning. I heard a very high-pitched whine (the sound you get when you have a bout of tinnitus). I looked up above me at the stars. Just as I did, one of the stars blinked out. Five seconds later it flashed back on momentarily and faded away again. It reminded me of how Cuttlefish use their Chromatophores to change their colors. The object started moving very slowly in a southerly direction. Every five seconds it would fluoresce, then fade away again. After a minute, it was out of sight..
