The full moon will appear a bit dimmer as it rises on Friday night. That’s because it’s due for a special kind of lunar eclipse.

The Feb. 10 event is called a penumbral lunar eclipse. That means the moon is passing through the fuzzy outer ring of Earth’s shadow. Unlike a partial or total lunar eclipse, the moon won’t have a bite taken out of it and it won’t darken to a deep red. Instead sky watchers will see a subtle shading.

For Arizonans, the eclipse will already be at its midpoint when the moon rises in the east around 6 p.m. The event will be over by 8 p.m.
