Boise, ID - Fireball

I was at my parents house this evening we were doing dinner and a movie nothing out of the normal for a Sunday evening for us or at least until my dad went out back to put his hens in for the night he came back in The back door and called my name I got up and ran to the back door and as I got to the back door I could see orange light lighting up our back yard and the neighbors all the way out to the alley then I saw my father pointing up and as I looked up I saw what appeared to be a big ball of fire approximately 30-35 feet overhead it than began heading east threw the trees and gaining altitude as it put distance between us and it fast as it got farther the orb started to look like a cross then just vanished we have no idea what we just saw it made no sound and if you held it next to the moon it was easily one third the size if not half the weird thing is our dogs acted like nothing was going on
