Dogs woke me up close to midnight needing to be let out for a nature call. I went out on back deck facing east and sat to relax. I looked at the sky and noticed a very bright light coming from the west as it came into view over the roof of my house. It moved at a steady moderate rate of speed and didn't vary course. I thought it was a satellite but it appeared much brighter and much lower. It travelled in a straight direction (east) as a satellite does but after watching it for about a minute or two it went up! It travelled at a considerable faster rate as it rose up and eventually went out of sight. It was the same color as a star or sattelite and I assumed that's what it was till it changed direction. It didn't change course and rise gradually, it simply reached a point and rose almost in a 90 degree angle. I was stunned and wish I knew what it was!
