Where’s the moon? Waning crescent

Some caught the waning crescent moon – the “old” moon – in the east before dawn Monday morning. Next new moon is April 26, 2017 at 12:16 UTC.

Hope Carter captured the moon Monday morning, April 24, 2017. She said Monday’s moon was: “… just a sliver and disappeared fast with the light of the sun on the horizon, but I managed to get this photo. A spectacular moonrise!! Happy Monday!”

A waning crescent moon is sometimes called an old moon. It’s seen in the east before dawn.

At this moon phase, the moon has moved nearly entirely around in its orbit of Earth, as measured from one new moon to the next. New moon will come on April 26, 2017 at 12:16 UTC; translate to your time zone.

Because the moon is nearly on a line with the Earth and sun again, the day hemisphere of the moon is facing mostly away from us once more. Over the past several mornings, we’ve been seeing only a slender fraction of the moon’s day side: a crescent moon. Because the moon moves eastward in orbit around Earth, the moon has been appearing closer to the sunrise glare. Will you see the moon on Tuesday? It would be very, very difficult since the moon will be so close to the sunrise!

Still, the waning crescent will be up there on Monday and Tuesday, nearly all day long, moving ahead of the sun across the sky’s dome. It sets in the west shortly before sunset.

This past weekend, the waning moon was near the bright planet Venus in the east before dawn. Steven Arthur Sweet of Lunar 101 Moon Book caught this spectacular shot of the moon and Venus Sunday morning over Toronto. See more moon and Venus photos from this past weekend.

As the moon orbits Earth, it changes phase in an orderly way. Follow these links to understand the various phases of the moon.
