CAPE CANAVERAL, Fla. — Better catch the moon’s disappearing act Tuesday — there won’t be another like it for three years.
The total lunar eclipse will be visible throughout western North America in the predawn hours — the farther west, the better, with Hawaii and Alaska having good views if skies are clear.
The forecast for Anchorage overnight is mostly cloudy with light snowfall.
As an extra treat, Uranus will be visible just a finger’s width above the moon, resembling a bright star.
Totality will last nearly 1 1/2 hours, with maximum totality around 1 a.m. Alaska standard time, as Earth passes directly between the moon and sun. The full eclipse runs from about 11 p.m. to about 5 a.m. in Anchorage.

Known as a blood moon, it will appear a reddish-orange from the light of Earth’s sunsets and sunrises. At the peak of the eclipse, the moon will be 242,740 miles away, according to NASA scientists. Binoculars and telescopes will enhance viewing, provided the skies are clear.
Among those providing a livestream of Tuesday’s lunar extravaganza: Griffith Observatory in Los Angeles and the Italian-based Virtual Telescope Project.
It’s the second total lunar eclipse this year; the first was in May. The next one won’t be until 2025. Plenty of partial lunar eclipses will be available in the meantime.
