Walked back to hotel room at around 2:00am Sunday morning in Primm, NV on 10/19/14 when my wife and I noticed a pulsating object over the mountains just east- southeast of Hotel. We were watching it as it hovered over the mountains rising but did not appear to be moving in any direction. About 5 minutes of watching this object my wife noticed another one more north of the current one. This other one was much further away but also pulsating with the same blue, green, white, and red lights. Both objects were over the mountains and appeared to be approaching each other after about 10 minutes. After about 20 minutes, we left the balcony that we were viewing these objects from so I am not sure where they went after 2:30am.
