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 1, 2018, is the first of two full moons for the month of March. The second full moon – coming up on March 31, 2018 – 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.
