Ross,
Are those time GMT or BST?
Cheers,
Dave

They are BST (="daylight saving time") - I manually set a +1 hour offset in the program over the summer months.

After a mostly cloudy day it did start to clear around 4pm, but at 4:34 there was dense cloud in front of the Sun, whereas just 60-sec later it had cleared enough to get this image:

Then the sky got much clearer from 5pm! :-(
