SIGHTING: COOS BAY, OR

Witness Testimony

"Star like object moving sporadically in northwest sky night after night.11/2/13 and 11/3/13 (11/4/14 100% cloud coverage tonight for us so unable to tell if still ongoing.) Me and my fiancee witnessed a bright object in the sky moving. It is (was) located in the northwestern sky and at first glance looks just like a star. Staring at it we noticed it moving slightly to the west or southwest direction, then all of a sudden it accelerated drastically and pulled a very tight 180 degree turn. Further observation of this UFO it continued to move left to right and in circles while slowing down and speeding up randomly. It would also dim and brighten back up at times during all this. That was 11/2/2013 and was visible once dark. The next night (11/3/2013) we observe the same UFO doing the same sporadic behaviors in the same area of the sky. I'd bet its still there but can't confirm due do 100% cloud coverage tonight (11/4/2013) in my area.At first thought it was probably just a plane til it pulled that tight 180 I knew then that it wasn't. Also know it isn't a comet or such, because if so would not act in such a fashion. Started to think it could possibly been a satellite but I was not sure. So I have researched a lot about our satellite's such as how they work and move/orbit exactly. After my satellite research I'm convinced this UFO is not a satellite.So what is this star looking object in the northwest sky moving sporadically night after night exactly? "
