Was staying up late Saturday night at a West Canyon Diablo ranch home. Sitting around with a friend talking we noticed what looked like an reddish/orange colored twinkling star very close to the horizon. We stood up for a clearer view and we notice this was no star. It was too close to the horizon to be a bright clear star. Pulled out my binaculars and saw it was over the rural area of the Bird Springs community (Navajo Rez). I could make out the distance ancient volcanic geo-formations in the background. We looked at this glowing light for about 2 mins and then it disappeared only to re-appear immediately (.5 sec, like on and off)to the left of where it was (keep in mind we were looking from a distance of 30 miles away). The distance between the 1st sighting and the 2nd sighting was considerable, about 2 fingers together, arms length in front of me. Maybe 1 to 1.5 miles apart. This one glowed/twinkled for 30 secs or so and then disappeared.
