If there is a day with zero sunshine how does the Met Office decide on
sunniest place? On the Met Office web site for the London and S.E summary
for last 24 hrs it has Odiham as sunniest with 0.0 hrs. (I'd hate to be
there on a cloudy day!). Is it possible that there was a few minutes in the
morning below the 0.1 hrs resolution quoted making it the sunniest? or does
the computer just pick a random site?

Computer glitch, I think, Dave. There was plenty of sunshine
yesterday in Scotland, northern England, and the Isle of Man.
Several sites reported between 4 and 5 hours. Durham was
sunniest on my list with 4.9h, though I guess Copley might
have beaten that. Kenneth?

It does raise the issue of what happens when legitimately there
has been no sunshine (or, similarly, no rain) anywhere in the UK,
but it's hardly difficult to add a couple of lines to the program to
cope with this in order to say something like "no sunshine anywhere".
I suppose it depends on whether anyone has the nous to realise
that it does occasionally happen.

Oh, bugger ... I've just noticed you referred just to
London and the Southeast. Clearly, my last sentence
applies.

Hi, Philip,

5.6hr Copley (R&D) - slightly better exposure than Durham Observatory.
