Item was stationary… then lights disappeared.

I had just opened the front door of my residence to take my dog out. I saw this bright blue light which was stationary. I took out my cell phone and snapped this picture.There was no sounds and then suddenly the lights disappeared and the cube shaped thing was gone… There were no sounds or flashing nav lights that you see and hear from a aircraft. It was not a commercial plane and I’m certain it was not a drone. I’m retired from the US Air Force and flew for 18 years as a boom operator onboard a KC-135 tanker. I am certain this was not a military, civilian or commercial aircraft . This object was spotted from the southwest. My home is located less than 5 miles from Calabash and the Atlantic Ocean.
