oct 4th, 2018, 815 pm. observed triangle shaped object hovering for about 20 min. had white strobe like rotating lights with numerous other red, amber,yellow, green lights flashing. I was facing north, observed object in sky north by north west. sky was very clear. it disappeared for several minutes, then came back, only for about 30 seconds then was gone. I continued to watch the sky and another 10 minutes passed by, then from same direction a disc shaped object shot across the sky at a very high speed, It also left, I guess the best term is a vapor trail as it shot away leaving a green hue on the object and vapor trail. that moment lasted maybe 4 seconds. from my observation, it was maybe less than a few 1000 ft in the sky. I observed it over a mountain top. unable to get pics.
