When can you see Earth's shadow? (Answer might surprise)

EarthSky

During Sunday night’s total eclipse of the moon, Earth’s shadow brushed the moon’s face. The eclipse is over, but, just like you or me, Earth still casts a shadow. Earth’s shadow always extends into space, in the direction opposite the sun. There are several good times to think about and be aware of Earth’s shadow. ...

See Earth’s shadow any evening, ascending in the east. You can see Earth’s shadow any clear evening ascending in the eastern sky. The shadow is a deep blue-grey, and it’s darker than the blue of the twilight sky. The pink band above the shadow is called the Belt of Venus.

Notice: Earth’s shadow ascends in the east at the same rate that the sun is setting below the western horizon

The shadow of the Earth is big. You might have to turn your head to see the whole thing. And, just so you’ll recognize it more easily, remember that the shadow is curved, in just the same way that the whole Earth is curved.


Alexander Kozik in California caught Earth’s shadow – that deep deep blue-grey line of darkness, just above the horizon – as the almost-full moon rose on June 1, 2015.

It's where the sun is still visible.

Astronomy camp, October 2013.

I have the good fortune to live in New Mexico, where I almost always have clear skies and a good view of the horizon. In the morning, just before sunrise, you see the same thing in the west.
