Where’s the moon? Waxing gibbous

It’s waxing toward the 1st of 2 full moons for the month of March.

The moon is now in a waxing gibbous phase, rising between noon and sunset, setting in the wee hours after midnight. You’ll always see a waxing gibbous moon between a first quarter moon and full moon, and, it so happens, the upcoming full moon – on the night of March 31, 2018 – is the second of two full moons for the month of March and so will be called by the name Blue Moon.

Any moon that appears more than half lighted but less than full is called a gibbous moon. The word gibbous comes from a root word that means hump-backed.

People often see a waxing gibbous moon in the afternoon, shortly after moonrise, while it’s ascending in the east as the sun is descending in the west. It’s easy to see a waxing gibbous moon in the daytime because, at this phase of the moon, a respectably large fraction of the moon’s dayside is now facing our way.
