Inside at about 9.30pm, we have no curtains on the windows as we are renovating. Lights all off in the house and we were in bed about to sleep and then look outside to the farm which backs onto a morass, and not too much higher than the tree-line a slow moving < shape of different coloured lights is moving across from left to right making zero noise. Definitely not a helicopter or a plane as we definitely would have heard it and it was be much faster if a plane. It was very close and very large. And moving the opposite way to what you think a triangle shape would be moving if it were a plane. I was a bit stunned and didn’t think of taking a photo unfortunately, really regret that.
