I suspect that that Farnborough minimum was reached quite early in the
night. I live within 20 miles of Farnborough, and by first light it was
overcast with the last signs of hoar frost rapidly disappearing. The
Farnborough minimum is a lot lower than I would have expected, and I
wonder if some data-logging error has led to the previous night's
minimum still being shown.
