"It's an awe-inspiring experience, there's no other word for it."
"You feel like a kid, you know, that you've never seen it before, you have no idea what it's gonna look like."
"Oh very excited, very..."
"The only way I can describe it is if someone had a dimmer switch on the Sun and just turned it down. You actually feel it going down... it's... argh, huh huh huh huh!"
Prof John Parkinson, Sheffield Hallam University - "A total eclipse of the Sun occurs when the Moon comes between the Sun and the Earth, and to us on Earth appears to completely cover the Sun. It's almost as if darkness descends from the sky, and then as the Sun finally disappears behind the Moon, this is really the most amazing sight anyone will ever see in their lives."
Whilst total solar eclipses occur on average about once every 18 months, it is actually very rare to see one.
This is because a solar eclipse only plots a very narrow path across a relatively small portion of the Earth.
The path of an eclipse is only 100-250km wide
It covers less than 5% of the Earth's surface
From any one point on Earth, you would only see a total solar eclipse every 375 years on average.
However, the beauty of physics means their paths can be precisely predicted and so amateurs and professionals alike travel around the globe to witness these phenomena.
"Well they...they become addictive."
"People tend to jump around and yell and scream."
Brian May, Guitarist from Queen - "A very unusual opportunity to see... to feel where you are in the Solar System, where suddenly you're looking in towards the Sun... you know, the mother of our Solar System. It is really something very exceptional."
As the moment approaches, the excitement begins.
But safety first!
Never look directly at the Sun unless you have very specific eye protection.
"Oh wow it's nearly there, it's... no, that's total, we can look now."
"No we can't, we can't look."
"They're all looking, over there."
"Don't look yet."
"They're all looking, over there"
Darkness falls and we have a total eclipse, in all its glory.
About three minutes later, it's over.
For the shadow chasers, it's been emotional.
"Yee haa! Yay!"
