Triangular in shape, 3 orange lights (1 at front, 2 on rear

was approx 3 miles distant, moved from north to south direction then shot up vertically, hovered, came towards us (west) then went to east and then just disappeared. All movements of craft were extremely precise and the movements were in 90 degree angles. There was no sound to be heard.

My brother (ex military) was seeing myself out after a visit and a cup of tea. We both noted something unusual in the sky. My brother's eyesight is better than mine, so he was the one who saw the finer detail (ie, number of lights and shape of craft). The craft made no noise It was a clear, calm night with a small amount of cloud cover to the east. There was nothing frightening to this incident, just a very unusual, unexplained thing to see. Every aircraft I've ever seen has the usual navigation lights. There were no regular navigation lights on this craft, just orange lights. We were both totally sober and substance free, therefore there was no way we were seeing anything that wasn't there. Did anyone else report this sighting?
