Subject: Eclipse of the Sun, 1 August


 

Hi all,

 

There will be an eclipse of the Sun on the morning of 1 August.  An eclipse of the Sun occurs when the Moon passes directly between the Sun and the Earth, so that the Earth passes into the Moon's shadow. Along the centre of the track, this eclipse will be total, while areas on either side of the track will see only a partial eclipse.

 

The eclipse will be total along a line extending from the Arctic, through Siberia, Western Mongolia, and Western China.

 

In the UK and Ireland the eclipse will be partial, ranging from over 40% in N Scotland to less than 20% in SW England.

 

In Ireland, the phase averages around 25%. Details are as follows:

SAFETY: NEVER look directly at the Sun, even with the unaided eye, as the heat and light can seriously damage the eye. And it is even more dangerous to look at the Sun with any sort of optical aid, such as a telescope or binoculars or even an optical camera viewfinder.

 

The only safe way to observe the Sun is with a special solar filter, available only from astronomical shops and dealers, or to project the image of the Sun through a telescope or a pair of binoculars onto a piece of white cardboard. Some people may still have special 'eclipse glasses' from previous eclipses, and these can be used provided that there are no holes or scratches in them. If in doubt, DON'T look!
