Triangular object with circle shaped lights flickers before disappearing.I was listening to the radio with headphones on at the back of my home looking out towards a field around 21:34. it was already dark and, out of nowhere, this triangular shaped object appeared moving in south direction with approximately 7 circles on the bottom of the object which were lit up. One for each corner, one in the middle of each side and one in the center. There was nothing flashing on it and there was absolutely no sound. I thought I was seeing things or maybe it was a drone and part of some practical joke but after about 5 seconds, it began to flicker before disappearing completely. It was if it was entering some kind of invisible state.((NUFORC Note: Source of the report elects to remain totally anonymous; provides no contact information. PD))
