3 to 5 craft with white and red lights flying erratic patterns over sierra vista / tombstone areaIt was shortly after sundown that my GF and I were sitting on my back patio, relaxing after dinner. As I have a habit of doing, I looked up at the sky (I enjoy sky watching) and noticed several objects to the north east that were moving. At first I thought there was a plane and the other objects were stars. After watching for several minutes I noticed there was a larger BRIGHT object and 5 smaller objects and the smaller ones were moving rather erratically. I mentioned it to my GF who also confirmed that she saw it. While she was watching I went inside and brought out my binoculars to get a closer look. They were very high in the sky.At this point, 2 of the 5 smaller craft had left the area, but 3 of the smaller ones were still there. The larger bright object had left also. Once we had the binoculars, we could see that the 3 smaller objects that were moving in what resembled figure 8 patterns but still very erratic, were circular. There was a pulsing red light in the center and a white light that ran around the outside in a clockwise motion. This continued for at least 2 hours (from 8pm to 10pm), and we went to bed, while this was still going on. These craft did not return the following or subsequent evenings.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
