Small Chevron shaped craft hovered silently above me at 200 ft. then zigged and zagged NW across Aurora.

Walking on Highline Canal path near Hinkley High School I noticed a small blinking light in the night sky.  At first I thought it was the light of a commercial aircraft at 20,000 ft. until it jiggled slightly up and down.  When the peripheal of my vision opened around the light I realized the light was at the bottom of a rectangular white craft slilently hovering approx. 200 ft. above me. Just above the tree line and above an apartment building. I stopped dead in my tracks, Rubbed my eyes and realized it was not an illusion.  The bottom of the craft as well as the sides were flat. The back side and front of the craft were angled. Much like the Chevron shape. It hovered motionlessly (except for slight jiggling up and down) over me for at least one minute.  Before it started off I could hear a "slight" air disturbance, and then it zigged slowly in a left angle about 50 - 75 ft. and stopped, then it zipped to a right angle and stopped, then left and stopped, then right and stopped in this exact pattern moving northwest acrossed Aurora towards the mountains until I could no longer see it.
Date may be approximate.  PD
