On the evening of October 27, 2004, and lasting past midnight into the morning of October 28, astronomers in North America will be able to observe a striking total eclipse of the moon.

About Lunar Eclipses

Lunar eclipses occur when the full moon passes through the Earth's shadow. Usually the full moon passes either north or south of the Earth's shadow in its monthly orbit around the Earth, and no eclipse occurs. When the moon skims the Earth's shadow, a partial lunar eclipse occurs. But on October 27-28, the moon will pass completely into the shadow of the Earth, producing a striking Total Lunar Eclipse.

Observers with telescopes and binoculars can watch as the edge of the Earth's shadow crosses individual craters on the surface of the moon.

A lunar eclipse throws an eerie reddish color across the face of the moon. Earth's atmosphere acts like a prism, bending a little sunlight into the shadow and giving it a copper tint. In essence, what falls on the eclipsed moon is the light of all the sunsets and sunrises on Earth.

Photograph the Eclipse

If you wish to photograph this eclipse, mount your 35-mm camera on a tripod and take scenic views with a red colored moon as part of your composition. Exposure times on ISO 200 film should be 1/60 second for partial phases at f/8, and 2 seconds at f/4 for the total phases. You may also photograph the eclipse through your telescope. Exposure times will depend on the exact setup of your equipment. Digital cameras allow even greater flexibility for photographing the eclipse.

Eclipse Photo Contest

The American Association of Amateur Astronomers is looking for the best photograph of the Lunar Eclipse of October 27-28, 2004. The photograph may be either color or black and white. You do not need to be a member of the AAAA to enter.
