A comment in another post inspired me to look at the temperature graph
for this morning during the eclipse. I quick look indicates that the
temperature continued increasing (it was morning after all and last
night was cold) but the rate of increased temporarily slowed at 10:00am,
matching the time of maximum magnitude of the eclipse (when the
temperature was 10.7C).

During the August 1999 total eclipse in Cornwall (totality around 11:11 BST)
the temperature dropped around 2 degrees in Penzance, but started recovering
so after the eclipse became partial. That was with quite thick cloud. During
totality it actually felt much colder than it was.

We did get a quick glimpse of today's partial eclipse. I got a good photo of
the October 1996 partial eclipse, which was very similar to today's. It's on
my web-site at www.easterling.freeserve.co.uk/wpage8.html

This comment makes me look at mine as well and there is a similar
slowing of the temp rise around 1000. TBH I wouldn't like to say it
was a direct result of the eclipse but that may have contributed.

Not as marked at the 11th August 1999 though:

Mind you that day was bright and sunny, this morning was over cast
with the cloud base only a few hundred feet above us.

My record also shows a slowing of the temperature rise centred on
the time of maximum eclipse. The sky here was clear throughout.

Yes you're right. Our temperature completely leveled out around that time.

Coincidence?

Coincidence?

With so many stations reporting very similar slowing or leveling in
temperature change I don't think so. Looking at Mr Stott's pictures
roughly 50% of the sun was obscured. That's a 50% reduction in the
energy arriving, must make a difference.

Not temperature but light levels, a correspondent kindly shared the
figures from their datalogger on a Cornish hilltop in 1999, in
explanation of why I was totally surprised that while things became
noticeably gloomier as the eclipse progressed, it wasn't until close to
totality that things started to fall of a cliff so to speak. There's a
plot on this page:

What I noticed very strongly in August 1999 and to a slightly lesser
extent yesterday was the change in the spectrum - the reds in particular
seemed to leach out of the colours. Did anyone else have the same
experience?

The period of darkness was very sharply defined, but the temperature at my
station did fall just over 2 degrees in around 40 minutes.
