I didn't really want to make a big deal of this but just watched a youtube video of a person also from my area post a video of an object very similar to the one I witnessed. Even more interesting, he filmed it within a week of the same time period I saw mine, only, two years prior. He says in his video he was filming on 4/9/14, I saw my object 4/16/16. I have always been fascinated by space and watching satellites so ever since I was a child I have always looked to the night sky. I'm very familiar with what satellites look like and also very familiar with what planes and helicopters look like in the night sky, what their flight patterns are and at what general altitude they fly at. I was outside sometime around 10pm having a smoke. I was looking up at the sky when I saw a satellite. I watched it float over my house traveling quickly south to north. I took another couple pulls on my pipe, was about to head in when I looked up to the sky one more time and saw a bright light, traveling slower than the satellite, about half the speed, going from north west to the south east. I noticed it had no blinking lights and no sound. It looked almost just like a satellite but roughly 6 times larger and brighter. Almost as if you were watching the star Sirius fly over. I wasn't making too much of it but it was peculiar enough I stayed outside and watched it fly over. As it got further away, the neighbors tree started to obstruct my view so I walked over to the other side of my lawn. As I was doing that, it simply just vanished from the night sky. At the least, I wanted to make a report to have on file because it seems I'm not the only one in Boise seeing these bright peculiar orbs/ufo's.
