Time: 06:44 am
While waiting for the Tiangong 2 satellite to reach its peak brightness at 34 degrees, I was looking around at the stars. I was looking west and then I saw a bright white light moving in the fog then disappearing and reappearing a few seconds afterwards (this happened 2 times) it was moving slowly across the sky at an elevation of around 34 degrees. It almost looked like when you see lightning in the clouds from far away, but it was more concentrated and brighter. There were no airplanes in the direction (west) that I was looking in (according to Flightradar24, the closest airplane was near Paarl and another one was still at the airport).
I have never seen anything like this and I have spent quite a while looking at the night sky.
