We were outside around 8:00 pm on the east bench of the mountains overlooking the city. Our view was the entire basin/valley. It was a very clear night with no winds or weather. To the direct west is Holloman AF Base.We noticed some orange orbs flashing on and off north of the base. They moved at great speeds across the valley. They stopped on a dime, would dim and then light up. A few would sit together in a formation and then turn off and move to another location where they would flash on again. We watched them for about 5 minutes, until they disappeared totally.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
