The morning of Friday 7 February 2020 was forecast to be sunny, after any early morning fog had cleared. It was foggy at home, but after heading off towards Uffington, I drove into the sun, only for it to disappear into low cloud and lifted fog, just after I had arrived at the lineside! For the next two hours, it remained more or less cloudy, with the exception of a couple of minutes, when 800006 & 800025 passed by with the 1A15 10:00 Bristol Temple Meads to Paddington GWR service.
