"Earthshine" on the dark face of a new moon is too weak to be seen in bright daylight.


When the sun is up in the sky, it is so bright that it washes out the light of the moon.

When the new moon is receiving light reflected off the earth -- and even if a moon is receiving light directly from the sun -- the sun makes the sky so bright that we usually can't see the moonshine during the day.

But sometimes there's a daytime moon.

It's delicate, elegant, serene -- as charming as a rainbow.

But in order to be visible, the moon can't be in a phase that is far from "full."

During the week before and after the full moon, the sun's position in the sky is far from the moon's location in the sky, so the light from the sun doesn't wash out the light of the moon.

To see a moon in the daytime sky:

  • Look within a week on either side of a full moon.
  • In the week before the full moon, you will see the daytime moon in the afternoon.
  • In the week after the full moon, the daytime moon is visible in the morning.

Keep on looking up in the sky.

Daytime moons are often visible, but you won't see them if you're not looking.
