Saturday morning the astronomy buffs will be looking up at the moon as we experience a lunar eclipse.

The full moon will darken and turn a reddish color as the Earth passes between it and the Sun, a slow-moving event that starts at about 4:15 a.m. MDT and ends in the 7 a.m. hour.

In the Mountain time zone, we'll be able to see much of the eclipse, starting with a slight dimming at about 4:15 a.m. until the brief minutes of "totality" at 6 a.m. We won't be able to see the satellite pass completely out of the Earth's shadow, because it will set behind the Bitterroot Mountains before then.

The weather forecast is not all that promising, but it's worth a look Saturday morning in the Bitterroot Valley. The last lunar eclipse was in October last year.
