Three lights with one being green, if connected, one can form a triangle; also stood in place while the lights flashed in a pattern.Friend noticed something odd in the night sky at around 1:50am east of our position. It appeared to be right over Vail, AZ, or our suburb of Rita Ranch. It was rather odd, when we noticed these three lights, that could form a triangle. The three lights began to move our direction without breaking formation, and then halted in one spot. It did not move from the position, but instead seemed to blink their lights and stare at us. I can only assume that they knew of us and watched with caution. The interesting thing about these lights were that they seem to be blinking in a pattern of sorts, and the left light happened to be the color green, but the other two lights were typical bright star-like lights (although far brighter and clearly closer). There is no full moon out, nor was it a new moon; the moon was not in my view when looking east toward these lights. The strangest thing was the coyotes were noisy, far nosier than usual. Typically you may hear a few coyo! tes yipper and howl, but only once in a blue moon (pun intended); this time every coyote was at it. I thought it may be a party down the wash since it was Fri/Sat, but it was rather late. Anyways, my friend an I viewed this mystery for a few moments and normally I'm able to point out whether or not it was a plane or helicopter, of course three lights flashing in a strange pattern is a little odd. The left green light was curious as you never really hear about colored lights unless it pairs with other colors (notably red, because then its a human craft). The lack of sound didn't help, nor the stationary position it developed. I wasn't going to wait around any much longer and told my friend to step outside and make sure I enter my house safely (I live across the street in the direction of the mystery), yeah, I was spooked and it was still there when I had entered. I want to point out however that Davis Monthan Air Force Base was to our north and northwest, but what we viewed was directly to the east. I failed to record the event, at 2am with only the two of us, like hell I'm staying around.((NUFORC Note: Witness elects to remain totally anonymous; provides little contact information. PD))
