BBC Eclipse programmes
By Chris Riley from BBC Science
Seventy-two years ago, only those who had trekked to the North of England witnessed the total eclipse of the Sun. This time around, through television and the Internet, the natural wonder will be watched all over the world.

There are many astonishing facts and record-breaking statistics accompanying this summer's total eclipse:
- A hundred kilometre-wide shadow will hurtle across the globe at over 3,000 km/h;
- It will be the most watched astronomical event in history, with 300 million potential viewers;
- A massive, million-degree centigrade corona will surround the solar maximum Sun.
But it is not just an astronomical record breaker. The BBC's coverage of the event is equally ground-breaking - twenty cameras, several kilometres of cable, satellite vans, microwave links, hot air balloons, weather satellites, trains, boats and aeroplanes and two years of planning have gone into the preparations.
Back on the 11 August 1997, BBC Science Executive Producer Phil Dolling was standing on a beach in Cornwall checking out the spot where the BBC will be broadcasting from this year.
"Nothing can be left to chance," said Phil. "We'll only get one crack at it."

With the wait now nearly over, he knows the magnitude of his task: "This is an unprecedented event in British broadcasting. The last time such an event hit mainland Britain was in 1927. The technology available then was not advanced enough to allow the BBC to cover it live.
"And when the next one crosses Britain in 2090, who knows what technology the BBC will be using? So this could be the one and only chance in history to cover a live eclipse in Britain on television."
In a suitably unique link-up, BBC Science, BBC News, BBC Online and the BBC's regional services will join forces to bring the eclipse to the nation across radio, television and the Internet.
From the moment the shadow touches the Earth's surface just off the east coast of North America, three Concordes will be standing by to chase it towards the UK.

From first landfall on the Scilly Isles, across South West England and on towards the Channel Islands, jet black polymer-covered camera lenses will be pointed skywards as the Moon slides silently across the Sun's giant disc.
Finally, a dozen other broadcasters will pursue the shadow towards sunset on the Indian continent.
The greatest view
There may well be a total eclipse somewhere on Earth every 18 months or so, but exactly where the Moon's shadow is projected onto Earth is rather a random affair and it is not always in a very convenient place from which to view it.
This August's eclipse follows an unprecedented trajectory that takes it across highly populated areas.
In three hours, more people will experience the euphoria of totality than during any other eclipse in history. Millions more will watch it on TV and there will not be another which is as photographed, filmed and gaped for many years to come.
"But there's more to an eclipse than gobsmacking statistics", explains Phil Dolling.
"It's all about emotion," he says, recalling the eclipse he witnessed in the Caribbean last year.
"It is people's reactions which will make the event come to life, and it's the millions of individual reactions to the Sun going out in the middle of the day which we want to capture on camera."
Under the weather
However, there is one thing that even the BBC and its two years of planning cannot control - the weather. Cloud is the bane of an eclipse chaser's life.

Among the professional eclipse-chasers will be Professor John Parkinson from Sheffield Hallam University, a veteran of seven eclipses. So far, he has not missed one because of cloud. And he is reasonably optimistic about this one.
"The three days around 11 August have almost all been clear down in Cornwall since 1996," he recalls. "There was only one sea mist day, on 10 August last year and it was strange."
It could turn out that Plymouth has brilliant sunshine and Falmouth just down the coast is under solid cloud. "But you pays your money and takes your choice," Professor Parkinson accepts with a shrug.
Just in case the nightmare comes true and the clouds do roll in on the big day, Professor Parkinson has a secret weapon - his bottle of "Eclipse rum".
"It might not make such gripping telly, but it's something to drown our sorrows in", he says.
Phil, on the other hand, has no plans to turn to the bottle, even if it is cloudy. Thanks to the battery of cameras - ocean-going, airborne and even spaceborne - the BBC will bring the eclipse to the nation whatever the weather.
BBC programmes will be covering the eclipse throughout and, wherever you are, you can always check BBC News Online to find out what is happening.
