On 1st August 2008 there will be a total eclipse of the Sun, visible from Canada, northern Greenland, Svalbard, the Barents Sea, Russia, Mongolia and China. From the whole of the British Isles observers will see a partial solar eclipse, with between 1/10th and 1/3rd of the Sun obscured by the Moon.
Total solar eclipses take place when the Earth, Moon and Sun are aligned and the shadow of the Moon touches the surface of the Earth. At mid-eclipse, observers within the lunar shadow briefly see totality, where the silhouette of the Moon completely covers the Sun, revealing the beautiful outer solar atmosphere or corona.
At its broadest, in this eclipse the lunar shadow is only 237 km (148 miles) wide but the shadow describes a path thousands of km long, traced out as the Earth rotates. The path begins in northeastern Canada, where observers will see the eclipse at sunrise, and then crosses northern Greenland, the Arctic, Barents Sea, Russia and Mongolia before ending in China where the eclipse is visible at sunset. On the ground the maximum duration of totality is 2 minutes 27 seconds but observers away from the centre of the track and at either end will see a significantly shorter event.
Away from the path of the total eclipse the Sun is only partly obscured by the Moon. This partial eclipse is visible across a large part of the northern hemisphere, including much of Europe and the whole of the UK, where it will take place in the morning.
In London the partial phase of the eclipse begins at 0933 BST (0833 GMT). Maximum eclipse is at 1018 BST (0918 GMT) when 12% of the Sun will be blocked. The partial eclipse ends at 1105 BST (1005 GMT).
Further north in the British Isles, observers enjoy a better view. From Edinburgh 23.5% of the Sun is covered and from Lerwick in the Shetland Isles, the Moon obscures 36% of the solar disk.
• Although eclipses of the Sun are spectacular events, they should NOT be viewed with the unaided eye except during the brief period of totality, which this time will not be visible anywhere in the UK. Looking at the partially eclipsed Sun without appropriate protection can cause serious and permanent damage to the eyes.
• The partial eclipse visible from the UK can be safely studied using purpose-designed solar filters available from reputable astronomical suppliers. Without these, the only safe ways to observe the Sun are to use a pinhole or telescope to PROJECT the Sun’s image onto card or to look at the natural dappled images under trees.
• On 1 August, some amateur astronomical societies and public observatories will be running events where members of the public can safely enjoy the eclipse.

looks like our observations are going to get on the tv.
-
If it's as cloudy as today, no one will see it here anyway.
-
oh but telescope really can help when it is as bright as the sun..
-
That reminds me. I have a telescope! ;D
-
For once, we had clear skies throughout the apparition. 8-) <--- me wearing my eclipse glasses. :D
-
Never saw a thing here.
-
we had clear spells which gave us a great view.. and we got on central news... which unfortunately (though my mother likes it) included a shot of Lizzie standing in front of me.. oh how sweet. My interview got cut though.. some cat saved its sibling...
-
I would not possibly be so bold as to speculate the method by which you were eclipsed by Lizzie whom I have met on several occasions. ;D All interviews get cut Sam. At least they didn't cut you out completely like they did to me last time! :bawl:
-
true..... but I think with you they are normally worried about the glare on the shot :laugh:
Oh and there were quite a few jokes about not needing the moon to move in front of the Sun with me around
-
Unfortunately, thick black clouds obscured any view of it here. :(
-
true..... but I think with you they are normally worried about the glare on the shot :laugh:
:bartmoon: ;D
-
I see on QI tonight that the Earth has 2 moons :bartmoon: :bartmoon:

Yes, you can read all about it HERE (http://www.space.com/scienceastronomy/solarsystem/second_moon_991029.html)

Drat - missed it!
:(
I'll have to catch the repeat on UKTV Gold.
-
:lol:

Some pics.

I wonder where they were taken from? Probably China. I saw the 2006 event from Turkey and the 1999 one from France. Even a 99.99% eclipse is third rate compared to a total so it's well worth making the effort to travel to see one.

You're right Clive, China.
Total solar eclipse

Thousands have gathered in locations in the northern hemisphere - including Jiuquan, China, where this photo was taken - to witness a total solar eclipse on August 1, 2008.

Thanks MB. That's where a friend of mine has gone to see it. :D
-
Looks as though they had a very good view.
-
He is a hoplessly addicted eclipse chaser and has to have his fix every year there is a total eclipse available. He has never failed yet and he's been observing them for 25 years!
-
... here is a tv clip of our observations... gosh I look like a numpty... :blush:

Oh, I thought we were going to see the in depth interview! ::) 8-)
-
Oh, stop it Sam, you look terrific. :thumbs:
-
I'm just concerned to know what he was doing behind Lizzie. It looked illegal to me and it was screened before the 9pm watershed. ;D
-
It would be a little difficult for her to see if he stood in front, Clive, you dirty minded.......... ;)
-
Yeah, but I know Sam! ;D
-
Yeah, but I know Sam! ;D
yeah you do ;)
-
Oh, I thought we were going to see the in depth interview! ::) 8-)
its probably for the best that you didn't see it!
-
Spoil sport! ;D
-
Yeah, but I know Sam! ;D
yeah you do ;)

Those glasses suited you better than the ones over there Sam <-- 8-)
-
indeed they do.... fortunately I don't have to wear glasses very often.. otherwise it would be a tragedy.
