I was hoping to listen to you programme after finishing a day at school here in Kuje, Abuja but the satellite connection to the internet was down for an hour or so and therefore I didn't get to hear the programme until later, when I used the fabled "listen again" facility.
5pm in UK translates as 6pm here and at that time the sun had just set behind a nearby hill which is captured in photo 2. This is the one which was closest to 5pm I think. You can't be too fussy though, on the internet even the pips on radio 4 aren't on the hour.
