Weather-permitting, star-gazers in the Northwest can watch a total lunar eclipse in the wee hours of Wednesday, Oct. 8.
It's the second part of an astronomical occurrence called a tetrad, which is four consecutive total eclipses with no partial eclipses in between, according to NASA. Earth's largest satellite will appear deep red, a phenomenon caused as solar rays are refracted — or bent — when light passes through the Earth's shadow. It's much the same reason that sunrises and sunsets appear reddish, according to earthsky.org.
Next week's full moon is also the Hunter's Moon, which according to folklore is the full moon after the Harvest Moon (the closest full moon to the fall equinox).
For viewers in the Pacific time zone, the moon enters penumbral, or Earth's shadow, at 1:16 a.m. Wednesday. The eclipse is total at 2:15 a.m. and ends at 6:34 a.m.
