Your guide to watching the blood moon in Arizona

A Blood Moon is Coming Tuesday Morning

Valley skywatchers, set those alarms now. A total lunar eclipse — one of the most visually stunning events the night sky offers — is happening in the predawn hours of Tuesday, March 3, and the Phoenix metro could not be better positioned to see it.

The show begins quietly. A partial eclipse starts at 1:44 a.m., when Earth's shadow starts nibbling at the edge of the full moon. Things get dramatic at 4:04 a.m. when totality begins and the moon transitions into its signature blood-red glow. The peak hits at approximately 4:33 a.m., and totality wraps up at 5:02 a.m. — all while the moon hangs in the western sky before sunrise.

That deep crimson color has a beautiful explanation. When Earth moves directly between the sun and the full moon, our atmosphere bends and filters sunlight, scattering blue wavelengths while allowing warm reds and oranges to reach the lunar surface. Essentially, every sunrise and sunset happening on Earth simultaneously paints the moon red.

The Valley is prime viewing territory because low desert humidity keeps the horizon crisp. For the best experience, head away from city light pollution — South Mountain Park, the McDowell Sonoran Preserve, or even the open stretches of the East Valley near Queen Creek or San Tan Valley offer excellent dark-sky conditions. No equipment is needed; this is fully visible to the naked eye, though binoculars will reward you with stunning detail.

One compelling reason not to hit snooze: this is the final total lunar eclipse visible from North America until late 2028. A partial eclipse arrives in August, but nothing like this. The moon will be sitting in the constellation Leo, under the lion's hind paws — a fitting backdrop for an Arizona morning.
