Beginning on Tuesday at 11.04pm BST, skywatchers
in the United States, Canada, Mexico, Central America, and the northern part of
South America will see the beginning of the show before the sun
sets.
Assuming the Great British Summer decides to
give us a clear morning, you will be able to view the transit from home - but
make sure you do it safely, with this advice from NASA:
Inexpensive eclipse shades have special safety filters that appear similar to sunglasses, but these filters permits safe viewing. However, with less than 48 hours to go, these may be tough to track down in time.
If you have binoculars or telescopes, special solar filters are available. However, never ever use a telescope without a filter or look directly at the sun - or you will irreparably damage your eyesight. And NASA warns not to buy solar filters that attach to the eye-piece, as these are not always safe.
But if there is a telescope to hand, find a screen and project the sun onto it. This will provide a magnified view of the sun, and the clearest way of seeing the transit yourself - but find a safe surface to project onto, as this can be a fire risk.
Pinhole projectors have the advantage of being easy and inexpensive, although their view is unmagnified. For advice on how to make one, check out the page at Stanford.
More advice is available at NASA's Transit page.
