Moon - by Brad

My 2007 calendar is Moon themed (you may have wondered what prompted the Moon phase gadget I added a few weeks ago). The calendar shows the cycles of the Moon and has an informational bit about the Moon. I have found this interesting and I thought that I would plagiarize March's tidbit...

One of the most eerie lunar phenomena takes place when the Moon, Earth, and Sun align during a lunar eclipse. As the Moon passes through the Earth's shadow, instead of disappearing into blackness, it glows bright copper-red. Even though sunlight is not directly illuminating the Moon's surface, some light waves refracted from Earth's atmosphere do still hit the Moon. As sunlight bounces off Earth's atmosphere, shorter blue-hued wavelenghts refract and scatter. The longer wavelengths at the red end of the light spectrum are the only ones that reach the Moon.

There is a full lunar eclipse coming up on March 3rd. However, for us who live on the west coast, we won't be able to see it. Don't be saddened, this just gives you a reason to live until August 28th, when we will be able to view the next one.

That's cool. Will you give us a reminder before August 28th? I probably won't be thinking about it enough to remember, but I know you will.
