Bright white orb hovers for over 4 hours.

Starting at about 10 o'clock at night I noticed an extremely bright orb in the sky to the south-west of the valley.   This object was brighter than any star I have ever seen, and it stood in a local position for what I witnessed to be at least 4 hours.   The light was a steady light, with no pulsations, no flickering at all. The orb was a solid white incandescent light, unlike the surrounding stars which seemed dull, as they flickered seemingly different colors, reds, blues, orange, or green.
 I eventually went to bed late at around 2 or 3 o'clock in the morning.   I cannot say for exactly how long this object was in the sky, nor did I see it leave its location.   But I do know that it was no longer in the sky the next night, or the 2nd night after the event.   This event happened in a clear sky, with no cloud cover, and a small crescent moon.
