Very bright pulsating light first observed at 45 degrees almost directly west. object would go into a stationary hover, list from side to side a distance double it's light brightness. It would then ascend or descend, hover then continue on a path west. I personally watched it for 5 mins before going inside and getting my room-mate and landlord to witness it with me. After i came back in from getting them there was now a vibrant green beam poking out of it's 7 o'clock position. The object was star sized compared to my distance the beam coming out made the object the circumference of a penny. It continued on with the actions and no pattern was observed with it's movement. After it had gone behind the tree line you could still see the light and it's movement through the trees.
