LOOK UP! Partial lunar eclipse visible tonight in Arizona

The moon will turn a coppery red tonight as it passes through the Earth's shadow.

The partial lunar eclipse will be visible in Arizona from 9:04 p.m. to 12:54 a.m. The maximum eclipse will occur at 11:02 p.m.

During a lunar eclipse, the moon passes through the Earth's shadow. The Earth's shadow is divided into two parts: the umbra and the penumbra. The umbra is the darkest part of the shadow, and the penumbra is the lighter part of the shadow.

As the moon passes through the umbra, it will turn a coppery red color. This is because the only light that reaches the moon is the light that is refracted through the Earth's atmosphere. The blue light is scattered by the atmosphere, so the only light that reaches the moon is the red light.

The partial lunar eclipse will be visible in Arizona from 9:04 p.m. to 12:54 a.m. The maximum eclipse will occur at 11:02 p.m. The eclipse will be visible to the naked eye, but binoculars or a telescope will provide a better view.

Lunar eclipses are a relatively common occurrence. They happen about twice a year. However, partial lunar eclipses are not as common as total lunar eclipses. This is because the moon must pass through the umbra of the Earth's shadow in order to create a partial lunar eclipse.
