On the morning of March 20, the moon will cover the sun, blocking out up to 98 per cent of its light in the UK. Since this eclipse will block so much sunlight, Britain's solar power industry is worried that it could cause power interruptions. Roughly 35,000 MW of power will be lost.
Added to this impressive occurrence, the evening before, the Earth and Moon will be as close together as they possibly can be, giving rise to a so-called Supermoon.
This makes the 2015 Spring Equinox eclipse a supermoon eclipse, because a supermoon, equinox and eclipse will all fall on the same day.
The partial eclipse, caused when the moon's orbit takes it in front of the sun, will been seen across Northern Africa, Europe and Northern Asia. Between 30% and 98% of the sun's light will be blocked out, depending on location across far northern regions of Europe and the Arctic. Source Mirror.
It probably won't happen again in my lifetime.
