Upcoming Primary Moon Phases

Future Solar and Lunar Eclipses

Events are ordered from the current date and use NASA eclipse catalog information. Visibility descriptions are regional; the local view from Claremont also depends on the event geometry, horizon, and weather.
Solar viewing safety: Never look directly at the Sun without certified eclipse glasses or a properly filtered solar instrument. Ordinary sunglasses are not safe. Optical filters must be mounted at the front of binoculars, telescopes, or cameras.

Twilight Guide

Civil twilightThe Sun is 0 to 6 degrees below the horizon. Outdoor objects remain easy to see.
Nautical twilightThe Sun is 6 to 12 degrees below the horizon. The horizon is still visible at sea.
Astronomical twilightThe Sun is 12 to 18 degrees below the horizon. The sky approaches full darkness.
Astronomical nightThe Sun is more than 18 degrees below the horizon, producing the darkest natural sky.

Moon Phase Guide

Waxing means the illuminated portion is increasing each night. Waning means it is decreasing.

The lunar age runs from about 0 days at new moon to about 14.8 days at full moon, then to about 29.5 days before the next new moon.

Moonrise and moonset shift later by roughly 50 minutes from one day to the next on average, but the actual change varies.

Photography Windows

Golden hour produces warm, low-angle sunlight shortly after sunrise and before sunset.

Blue hour occurs during deeper twilight when the sky takes on a cool blue tone and city lights become prominent.

For faint deep-sky objects, the best window is normally during astronomical night when clouds are limited and the Moon is below the horizon or weakly illuminated.
