For the first time this century, the sun will vanish behind the moon over the United States on Sunday.  You should have a fair look at it too...

Sky watchers in this part of the country will be treated to a partial disappearance of the sun behind the moon this Sunday (May 20.)  The eclipse will occur in the late afternoon or early evening in North America.

Over the duration of the solar eclipse, the sun won't vanish completely.  The moon is estimated to cover about 94% of the sun and a ring will remain around the moon for what is known as an annular eclipse.
