Large three lighted aircraft without any blinking

I went outside just after midnight to smoke a cigarette on the porch. Looking up in the sky I spotted ths objectin the sky. At first I dismissed it because it didn't seem to move, but all of a sudden it began to move. It had three lights to it, and seemed very high in the sky, and far up. Once it started to move I noticed the lights were not blinking. Most aircraft thier lights blink so thought this was weird. Once it went to the right of a tree, and telephone pole I lost site of it.
Not saying it was a UFO, but seemed wierd so thought I'd report it.
