View at EarthSky Community Photos. | Meiying Lee in Taipei, Taiwan, captured the images to create this moon composite across a single evening, July 18, 2021. It shows how the angle of the moon – and the color of both the moon itself and the background sky – change from when you might first spy it in late afternoon, until after midnight, when it sets. Meiying told us: “This photo is a combination of different azimuths in the sky of a waxing gibbous moon in the same night. You can observe the changes of the moon’s disk in the sky and the color of the moon in different sky.” Thank you, Meiying!
Waxing gibbous: more than half-lit, less than full
You’ll see a waxing gibbous moon between a first quarter moon and full 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. Take a look at Meiying Lee’s illustration above to see the change in the angle and color of the waxing gibbous moon, as it’s visible from afternoon until after midnight. The moon at this phase is easy to see in the daytime because, at waxing gibbous moon, a respectably large fraction of the moon’s dayside faces our way.
