The
day the sun went out.
Paul Stephens reports from the Solar Eclipse 1999
I'm far too decent a person to even think about renting my house out
for £10,000 to gullible tourists (honest!), so I was at home near Lands
End in Cornwall on August 11th to witness the much-heralded "last
solar eclipse of the Millennium".
Like almost everyone else in the West of England, I didn't actually get to see
the sun, since there was heavy cloud cover throughout the eclipse period. What
those of us near the line of totality did, however, experience was the darkness
as the moon completely covered the sun's face.
For the first hour, as the moon partially eclipsed the sun, there
really was no difference in light level - in fact it had been darker at
8.30am, due to cloud thickness, than it was at 10.30, with the sun nearly
half covered. By 11.00, ten minutes before totality, it had become quite
murky, although it was still hard to tell whether this was due to the
eclipse or the clouds.
At 11.10am the light faded, and did it amazingly quickly; in less than
30 seconds we went from daylight (albeit of a fairly gloomy variety) to
late dusk, as if someone was operating a celestial dimmer switch. The sky
to the west and east was as dark as night, but it remained light above the
horizon to the south and (to a lesser extent) north. As a result we
weren't in complete darkness, but were instead lit
faintly and indirectly
by sunlight bouncing off the Earth's atmosphere beyond the moon's
shadow.
The effect was similar to pre-dawn and post-sunset, two times of every
day when we're lit in this way.
However, with its dark overhead sky and lighter horizon in multiple directions,
the totality more closely resembled being directly under a heavy bank of storm
cloud with clear weather in the distance. That's something you experience quite
often if you live on the edge of the Atlantic, and although totality was far
more dramatic (and happened far more quickly, since low-lying storm clouds
seldom travel at 1,000 mph), it had a definite familiarity to it.
As well as blocking our view of the sun, the heavy
clouds denied us two other eclipse effects. Because the light was so
diffused, we saw no approaching shadow on the sea or the clouds, and no
unusual light patterns on the ground. And if there was a drop in
temperature, it was too small to notice - not surprising, as instead of
being plunged from bright sunlight into darkness, we merely went from gloom
to greater gloom.
The local animal population didn't seem over-impressed
either. The cows in the next field stayed resolutely upright during the
totality, as did my neighbour's dog, although the crows left their vantage
points on the telephone wires for the period of darkness. Much more excited
were the human visitors who crammed onto the hill behind us, and (rather
precariously) the clifftop a few fields away. There was whooping and
cheering, plus the popping of dozens of flashguns (which will, no doubt,
soon result in dozens of people wishing they're read their cameras'
instruction books). They were determined to make an event of the eclipse,
and, clouds or no clouds, they seemed to be managing it.
I did experience one phenomenon which eclipse veterans had promised us -
the unbelievable speed with which the two minutes of totality passed.
Without seeing the sun it was impossible to tell when totality actually
began and ended, but it seemed more like a few seconds before the sky in the
west began to brighten again. Then the celestial dimmer switch - by far the
most impressive feature of the cloudy eclipse - was turned up as quickly as
it had been turned down, and we went from dusk to dawn in another thirty
seconds.
At that point I assumed it was all over - the moon continued to partially
obscure the sun, but we couldn't see it, and the light level had returned to
that of an ordinary cloudy day (a type, incidentally, far more frequent in
Cornwall during August than the tourist industry would like you to think).
However there was an unexpected bonus. Later, through a gap in the heavy
cloud cover, though still screened by higher layers, there was the sun, with
the black moon covering its bottom-left quarter. I saw it for around three
seconds before the low cloud closed in again. I'm glad I did, although it
reminded me of what we would have seen if the weather had been
fine.
Was the cloudy eclipse worth seeing? Definitely - just experiencing the
light level altering that quickly was quite extraordinary. Was it moving,
mystical or life-changing? Basically, no.
It went dark, then it got light again, but it does that every night, and
we understand the reasons why it happened during the eclipse every bit as
well as we do the process of night and day. In fact, having seen both, I
think that a dark shadow over the land is well beaten in the awe-inspiring
natural beauty stakes by a really good sunset over the sea. Even in cloudy
Cornwall I shouldn't have to wait until 2090 to see another one of those.
POSTSCRIPT
This
is what the sky looked like in west Cornwall at 11.11am the day after the
eclipse - perfect, with not so much as a wisp of cloud anywhere near the
sun! In fact the sun beat down relentlessly all day. Game, set and match
to the Cornish weather yet again!
Meanwhile,
if you watched the BBC's overcast and occasionally rain-soaked eclipse
coverage from Marazion, near Penzance (and didn't those poor presenters
work hard?), here's what Marazion and St Michael's Mount looked
like just 24 hours later. Makes you sick, doesn't it?
