Where’s the moon? Waning gibbous

The moon is now up from late night until early morning. Last quarter moon will be March 9. New moon will be March 17.

Are you looking for the moon and not finding it? That’s because the moon is now in a waning gibbous phase: less than full but more than half-lighted. It’s rising later at night and appearing in the predawn sky and in the sky after sunrise. Last quarter moon will come on March 9, 2018, at 11:20 UTC; translate to your time zone.

A waning gibbous moon can surprise you if you happen to be out late in the evening. It rises eerily some hours after sunset, glowing red like a full moon when it’s near the horizon.

Sometimes it looks like a misshapen clone of a full moon.

A waning gibbous moon is sometimes seen in a blue daylight sky. Here it is on March 5, 2018, caught by Sam Rowland in Zamboanga City, Philippines.

Get up before dawn for a great view of the moon and the morning planets!

A waning gibbous moon also initiates a rash of questions about seeing the moon during the day.

If it rises late at night, you know the waning gibbous moon must set after sunrise.

In fact, in the few days after full moon, you’ll often see the waning gibbous moon in the west in early morning, floating against the pale blue sky.
