It was around 8:00 PM and I was at home located at 28 Plein Street. I was outdoors testing a setup for astrophotography with my DSLR Canon 100D. The constellation I was imaging was Leo in Canis Major. I recall being disturbed by turbulence in the air around me and looked up and saw an unusual triangular shaped craft glide overhead at low altitude. I estimated a height of about 100 m later on and about the size of a large passenger jet. It had an array of circular shaped lights in an isosceles triangle underneath with a faint almost invisible infrared orange-red like colour. I would have easily not seen this if my eyes were not adjusted for night vision. I thought it was some stealth plane as it was completely silent with no noise whatsoever. I have flown in planes before even gliders and this clearly had me puzzled to its identity. I recall sketching a drawing and going to the airfield but no one knew its identity. Later I did a 3D model of the aircraft to show people a glimpse of what it looked like with its lights. This was posted on Quora. https://www.quora.com/Do-UFOs-really-exist-4/answer/Chaven-Yenketswamy
