The right time to watch the comet is at the new moon January 21, 2023 Almost unlike the full moon that shone on January 7th. The moon is between the earth and the sun. In this position, exactly half of the moon that has moved away from the Earth is illuminated. So we don’t see the moon – and the night stays mostly dark. Comet C/2022 E3 (ZTF) is particularly good for admiring the new moon.

According to Haus der Astronomie, the days after that, shortly before the end of January, would also be ideal: “The comet has almost reached its maximum brightness at about 5.5 mag, and the moon in the first quarter sets in the second half of the night,” according to experts. .

The maximum brightness of 5.5 mag is very impressive for a comet, and you might even be able to see it with the naked eye under very dark skies. “But you have to know exactly where in the sky to find him.” Search maps of the Society of Friends of Stars, star atlases or suitable mobile applications can help.
