Instantaneous drop in temp (4 degs)and dewpoint on passage of front
Monday.

Visibility afterwards was stunning with distant features merely
appearing "small", ie no haze - the sort of visibility that occurs
only a few times each year at best

I tried to photgraph Ely Cathedral (40 kms distant) but couldn't
manage to align the camera to look through my (birders') telescope
properly!

But this link show King's College, Cambridge from 18 kms distance.

... yes, quite notable and it looks as if we are dealing with this clean
air mass for several days to come.

Amazing. That reminds me of approaching Las Vegas by car. When its
skyscrapers first came in view across the desert, it looked close enough
that I thought that we would be there in another 15 minutes. Half an
hour later, we seemed to be no nearer.

Once I experienced such a day at the top of Helvellyn, with crampons on
my boots thanks to the previous night's snowfall. To the east we could
see the Peninnes, to the north the hills of Dumfriesshire & to the south
a hill I later identified in Lancashire.

I think the Dumfriesshire hills were something like 110km away. Of
course from over 3,000 ft you _should_ be able to see a long way, but
vis is often around 2 metres on Helvellyn :-(


Slightly OT, the two best atmospheric phenomena I've seen were a
magnificent display of the Perseids seen from the top of the The Wrekin
(before the current light-polluting town of Telford was built), and a
full "glory" from a glider at (ahem, let's call it) 12,000 feet over the
Great Glen. (For Jack: very strong wave off Mull, we had no oxygen with
us and even at 120kt with the brakes out were still not descending. So
the only way to come down was to spin :-)

That would have put you at around St.Ives/Newmarket kind of distance?
Whereabouts are you located, as you'd have been high up?(ish)

No, I was to the south of Cambridge near village of Chrishall on high
ground (circa 140 metres asl) just across the border into Essex.
