I was outside for cigarette, looking up at the moon in south. I turned to east and saw a bright light in eastern sky proceeding from south to north. The light was a bright white ball with a lighter white light in the shape of a boomerang at the nose of the ball. The light proceeded at a good rate of speed, slowed down for a short period, then regained speed again. There are large trees in town so I lost sight of it after about 30 seconds. I went north down the street to see if I could continue to see the light but it was gone. The sky was clear and the stars were out. It is winter so the temp was approx. -25 degrees Celcius. No wind. It was quiet and no other aircraft in area. The ball of light did not make a sound. The shape would be if you took a boomerang, turned it so that it was pointing north and the ball of light was behind the pointy part. The ball was bright and the boomerang part was lit but not as bright as the ball. I've seen shooting stars before and this was not that. I don't know what it was but it definitely affected me. I can't seem to get it out of my head. I wasn't nervous or scared during the sighting. I am more intrigued and would like to know what it was. I was hoping that it might turn and come back towards town but once it disappeared I never saw it again.Unfortunately, I did not have my cell phone with me and did not have time to run into the house and get it.
