6 objects in 50 minute duration: 4 lights and 2 dark objectsThis occurred on Monday night, October 7th, 2006. It began at 7:35 PM and lasted until 8:25 PM involving 4 separate objects, each seen at different times during the 50 minute duration. The first object was seen at 7:35 PM as I was leaving for a security patrol. The object was seen by me and my co-worker, then later only by me. The first object came from the south west and moved to the north east. This object was a white ball of light. It stopped 2 times completely, then continued across the sky very slowly. There was a discernable darkness around the object. Though it did not pass over any major stars, there seemed to be a solid object and not just a light. An airplane (a regular commercial airliner), about 3-4 minutes into this, came from the north west. Within 30 seconds of the airplane appearing, the light we had been following simply vanished. I then went on my security patrol. About 5 minutes into the patrol, directly overhead, a small light appeared. It then began to grow in intensity and travel in a southerly direction, reaching a -2 or -3 magnitude, not quite the brightness of Venus. At 8 PM, I reached about the midpoint in my security round. I saw another light, this time very dim, moving from south east to the north east, crossing through the constellation of Pegasus. At 8:10 PM, I went to the same spot where the other security guard had seen a triangular UFO fly over him two nights before. I saw nothing at this point, and left to continue my round. A light caught my eye in the mountains to the north east. A very bright light near the top of the mountain range. I went back to my previous position to get a better look. I am very familiar with this mountain range, even in the dark. More pointedly, the stars rise over this mountain range, giving a clear outline of mountains themselves. If Venus is normally a magnitude of -4 to -5, this was a magnitude of -7 at least. This light/object moved up and down from the top of the mountains, into the sky about a degree or two. It also moved side to side and two times, and twice increased in brightest and moved in such a way that I felt that it was approaching, however, it never did move overhead. After calling the other guard about this object, and asking him to come out, it faded to the same magnitude of the star I was watching rise over the hill to its left. It then increased in magnitude and then vanished. This is similar to another sighting I had on September 29th on an adjacent mountain range. I was able to rule out a motorcycle or car headlight in that the light/object clearly moved above the horizon, something a normal vehicle could not do. Once the other guard arrived, he noticed an aberration in the night sky. He pointed to it, and I saw it as well. 2 objects flying low in the sky. One that seemed to be darker than the night sky, traversing over the background stars and another "ghostly" object behind it that also obscured the stars in the background. These objects came from the areas where the bright light had been and traveled beneath the constellation Pegasus in a north to east trajectory. Not feeling comfortable about being in that location any longer, we then headed back to our office to complete the patrol.
