Longest partial lunar eclipse in more than 500 years happening this week

Clouds may block the viewing of expected partial lunar eclipse early Friday morning across Eastern Washington and Oregon.

TRI-CITIES- Star-gazers in North America will get to witness a rare event in the sky early Friday morning, if the weather cooperates in Eastern Washington and Oregon!

The longest partial lunar eclipse since the 1400s will occur beginning late Thursday night. The peak of the eclipse is expected to happen just around 1 a.m. PST Friday. Astronomists are expecting November’s full moon to turn a reddish-orange color for more than hour.

Unfortunately, the forecast calls for overcast conditions and showers Friday morning in the Tri-Cities, Yakima and Walla Walla. If the clouds part, the event should be visible.

According to NASA, the eclipse will last three hours and 28 minutes, the longest partial eclipse of this century and the longest in 580 years.
