I've seen L6 type once, but it was a completely luminous ball in a kind of "colorful white". Its light behaved like plasma or a kind of "static white fire" and some colourful light beams across the UFO's body, and that white looks like came form all primary colors lights shining at once. All in the middle of the night, over Los Andes. I was able to see it up close because I used a modern army monocular that belonged to my father (he was also with me observing the phenomenon). It rapidly traversed from one mountain summit to another in just 2–3 seconds—covering hundreds to possibly thousands of meters between peaks. Later, it descended to a position below the summit but still well above the ground, hovering stably (not touching down) in a lower position along the mountain slope. Precisely when I and my father viewed it up close through the military monocular. It was there about 40 minutes and then it went upwards, untill that luminous dot disappeared between stars. It occurred around late autumn 2003 (likely April–May in the Southern Hemisphere, possibly a Sunday night in May), over the Cordon del Plata (Cordón del Plata), a rugged, high Andean range in Mendoza Province, Argentina. submitted by /u/Inevitable-Ad4868 [link] [comments]
