Excitement is building about the partial solar eclipse that will be visible across South Holland.
The phenomenon is set to darken the skies tomorrow and nothing like it has been seen since 1999.
Graham Winstanly, of the Lincolnshire Astronomical Society, said: “In Lincolnshire we will see the sun 90 per cent covered.
“The process will take around two hours, starting about 8.30am.
“Unfortunately it’s forecast to be cloudy so there is a chance we won’t see very much. But it will go a bit darker around 9.30am as the eclipse reaches maximum.”
A total eclipse will completely blot out the morning sun on the Faroe Isles, 200 miles (321km) north of Scotland. However, the UK will not see another total eclipse until 2090.
The last total eclipse visible from the UK was on August 11, 1999, when the moon totally covered the sun as it crossed over Devon and Cornwall and thousands of people descended on the counties to experience the eerie spell of daytime darkness.
Friday’s eclipse has especially excited primary school children studying space as part of their curriculum.
Lucy Burton, a teacher at Tydd St Mary Primary School, said: “All the classrooms are planning to spend some time outside viewing the eclipse.
“Some classes are making pin hole projectors or other forms of safe viewing techniques. We all feel the children will benefit from the experience.”
Spectators are being warned taking pictures of the eclipse on a smartphone could put people at risk of blindness.
Eye experts advise indirect viewing, using pinholes and facing away from the sun.
