I was on my laptop facing the window with a western view of downtown boise. i saw a bright object moving around above the buildings. at first i thought it was another helicopter, as they are always buzzing the city. it had no pattern of movement. it seemed to move randomly. the object was a dull orange or amber color and suddenly got very bright. i thought a helicopter had its search light on and was pointed towards my building. that is when i really started paying attention to it. i watched it move around over the buildings and its brightness dimmed. i ran to the bedroom and grabbed the binoculars. i came back to the living room and the object stopped moving. it froze in place for a few minutes. i know it was still because a star was just behind it in view and i could tell it was stationary. after about 5 minutes it started to move from my left to right, or to the north. the brightness dimmed quite a bit and its brightness pulsed a few times before getting very dim and it moved faster as it left my field of view.
