I was pulling out of grayhawk golf club at 8:30. as i was waiting to pull onto thompson peak i noticed 4 hugh lights off to the se fairly low in the sky...Barely over treetops. being familiar with the area i knew there were no lights that large and grouped together that i had ever seen. what caught my attention was the fact they (lights)were so bright and very large, and they seemed to stay in exactly the same place as a unit, but did tilt a few times where it then looked like a rectangle with lights in four corners. then one of the lights would break off and. become smaller. then it would move away steadily and travel sw. the main ship seemed to stay in a hovering position for sure, just moving. i turned east on thompson peak and tried to see it over the trees. so i knew i had to get in a clearer point of view. i headed south on pima rd and followed the hovering ship four 4 miles. darkness had totally exposed all stars. weather was crystal clear. as i got to the bottom of pima i was too low to see it so i headed back up the hill (pima). i went on to the rooftop terrace at my house when i got home but could not see any of it anymore. i did not hv my camera phone with me.
