Appearing with a reddish tinge from Earth's shadow and a faintly illuminated silver sliver on the lefthand side, the "beaver moon" hung in the sky, with the eclipse continuing into early Friday morning.

The celestial spectacle was the longest partial lunar eclipse "within a stretch of 1,000 years."
