I was coming home from Scouts in my dads car, just between Orem and Springville on the Interstate, I was looking up at the moon, I think it was full that night. Next to the moon was a small little star, which I thought was odd, because I'd never seen a star that close to the moon before, so I watched it. After about 5 minutes of watching it, it suddenly took off, it was out of site in about 1/2 a second. I was surprised at first, then, remembering a book about UFOs I had read, took note of the date and time, and wrote it down, the paper, I have since lost, so the time is fuzzy. I know it wasn't a shooting star due to the fact, that it was just sitting there for quite a while.
