As i drove into my driveway just before 9:00 pm out in the talavera desert on the other side of the mountains of white sands missile range. a triangular outline caught my eye looking west. i was in the air force and am able to identify aircraft. the object was large and stationary, holding the same position throughout the sighting. it appeared to be reflecting the light from new mexico state university stadium which was lit up for an event as it was low on the horizon. from my viewing position the “a mountain” blocks the city lights so i had an unobstructed view with no light pollution. after about 20 seconds the outline was no longer visible slowly dimming and an orange red light emerged, dimly at first then brightly. the light dimmed again with nothing visible then after another 40 seconds the light began to brighten in the same position and same color. the light had increased in size and was visible for another 20-30 seconds then dimmed and never reappeared.
there were 3 witness in my vehicle all of which saw the light and shape. i looked away to grab my camera and during that time one of the witness said it rotated, i did not see the object move. i turned my camera to the object but the batter was dead. i don’t believe the battery was affected by anything other than my own fault for not charging it.
