I was outside on our reservation.There are no lights in the area, neither house or street or cars. I was taking pictures as the sun dropped below the mountain. Just as it dropped to complete blackness I saw to the left a tiny white cloud like whiteness with 2 flashing lights.. one on the left was bright white and the one on the right connected was bright red..then it was like a flash of white and to the right a little distance it turned into this perfect circle of white ness.. I mean a perfect circle.. and it kept getting bigger and bigger .. as it did to the right of the circle.. sorta sideways was a pulsing and vibrating opening in the sky... suddenly inside the top arc of the circle became this left to right beautiful turquoise vapor or cloud. I tried filming but all i could get was the white opening.... after it started to fade away suddenly 2 basketball size circles.. appeared moving east to west across the groundright in front of me ....the 2 circles really scared me cause they were 3 feet in front of my feet.. My first thought was it must be the military circling overhead cause they saw it too... but as I looked up above me there was nothing ..I was a bit shaken and slammed my door shut. When I got back to the city, everyone else was talking about some other kind of sighting.. noone had talked about the same visual I had.. I called another tribal member and asked did they notice they sky and they said they were inside but the dog was running back and forth in the house barking.
