    Your guide to the total lunar eclipse
    Tuesday's event will be the second in three years

    Tuesday morning, Aug. 28 brings us the second total lunar eclipse of 2007. Those living in the Western Hemisphere and eastern Asia will be able to partake in at least some of this sky show.

    The very best viewing region for viewing this eclipse will fall across the Pacific Rim, including the West Coast of the United States and Canada, as well as Alaska, Hawaii, New Zealand and eastern Australia. All these places will be able to see the complete eclipse from start to finish.

    Europeans will miss out on the entire show, as the moon will be below the horizon during their mid and late morning hours.

    What to look for
    The eclipse will begin when the moon enters the faint outer portion, or penumbra, of the Earth's shadow about an hour before it begins moving into the umbra. The penumbra, however, is all but invisible to the eye until the moon becomes deeply immersed in it. Look for a slight hint of shading or smudginess on the eastern (left) edge of the lunar disk about 40 minutes after the moon first enters the penumbral shadow.

    The most obvious part of the eclipse will be when the moon is passing through the dark umbral shadow of the Earth. On this occasion, the full moon will track just to the south of the center of the Earth's umbra; deep path almost through the center of the umbra which will result in a total phase lasting an unusually long 1 hour 30 minutes (the maximum possible is 1 hour 47 minutes).

    Because some of the sunlight striking our planet is diffused and scattered by our atmosphere, the Earth's shadow is not entirely dark. Enough of this light reaches the moon to give it a faint orange or reddish glow even when it's totally eclipsed.

    At greatest eclipse the moon's southern limb will pass 1,039 miles (1,672 km.) from the outer edge of the dark shadow. This should produce a relatively dark eclipse, with the moon glowing a dull coppery color along its lower portion and a deep brown or gray over its upper portion. encourages viewers to estimate the Danjon value a five-point scale of lunar luminosity ("L") to classify eclipses at mid-totality.

    The beginning and ending of a lunar eclipse happens simultaneously for every viewer, unlike an eclipse of the Sun. Hence the simple schedule below holds for all places:

    Where you can see it
    As for the region of visibility for this eclipse, it pretty much is the "flip side" of the last eclipse, in March: Whereas Africa, Europe and western Asia had ringside seats for that late-winter spectacle, this time they are completely out of luck. The timing of the eclipse comes during their late morning and early afternoon hours, with the eclipsed moon below the horizon.

    Conversely, almost the entire Pacific Ocean is turned toward the moon during this August eclipse. In fact, at mid-totality the moon will appear directly overhead for a spot over the open waters of the Pacific, roughly 1,800 miles (2,900 km.) south of Hawaii.

    If you can get to Antarctica for Feb 7 there will be an annular solar eclipse. Thought I'd mention that in case you wanted to see the sun's ring.
    Political correctness is based on the principle that it's possible to pick up a turd by the clean end.
