See brightest star Sirius at midnight on New Year's Eve
Dog Star Sirius reaches its highest point in the sky around midnight every New Year. For this reason, it might also be called the New Year's star.
Tonight … Planet Uranus in moon's glare
The December 27 moon is close to the 7th planet, Uranus. The lunar glare glare will make it tough to spot, but notice stars nearby ... and come back when the moon is gone.

Tonight … Planet Uranus in moon's glare
After the moon moves away, it'll take patience to locate Uranus in front of the constellation Pisces. A detailed chart will help, too.
