UFO Sighting in Missoula, Montana on March 31st 2016 – Bright star like object wavering movement slowly across sky, changed direction 90 degree away and quickly vanished

Arrived home last night and as I drove into my driveway I saw a bright light up in the sky ahead of me. Approximated 50 degrees up, clear night so not sure what the actual distance up was. First glance I thought it was a star, but as I exited my car and watched it, I noticed it was slowly moving in a N/NE direct. Seemed to quiver and was not moving in a straight line. As I walked into my backyard to get a closer look, the object appeared to make a 90 degree turn to the east and quickly dimmed and vanished as though it sped quickly away and/or upward. The time was 9:16 pm. I have seen these type of objects before so the pattern of the movement was familiar and similar to prior sightings. I had several sightings of this sort last summer. The first of this such object was almost a year ago to date. Reaction was mostly excitement and intrigue as again, this is not my first sighting of these objects in this area. At the time, and even back to these moments of describing the sighting, I get goosebumps, a chill down my back and a bottomless feeling in my stomach.
