Last night about 3 am I watched from my home in the Catalina Mountains looking south two clusters of 4-5 shapes hovering over South Tucson. One of the groupings of shapes were bright white in color. The color intensity would increase and decrease. The second grouping which I felt were further South seemed more amber in color. I counted up to 6 shapes in the Amber grouping. I watched these grouping for an hour and a half as they slowely moved south. During this time a hellicopter closer to midtown fly east to west. Whoever was flying this hellicopter must have seen these lights. This entire viewing and description reminded me of the Phoenix Lights several years ago.
