Full Wolf Moon Eclipse A penumbral eclipse of the Moon occurs on Friday 10 January, 2020. At maximum eclipse, 90% of the Moon's disc will be partially shaded by the Earth, which will cause a slight shadow gradient across its disc; this subtle effect may be visible to careful observers. No part of the Moon will be in complete shadow. The eclipse will last 4 hours and 5 minutes overall, and will be visible from Africa, Europe, Asia, Alaska, and Australia. Winter Circle The Winter Circle , also known as the Winter Hexagon, is a prominent winter asterism formed by seven stars prominent in the winter sky. These are Capella in Auriga, Aldebaran in Taurus, Rigel in Orion, Sirius in Canis Major, Procyon in Canis Minor, and Castor and Pollux in Gemini constellation. There is also a patern within the Winter Circle. It's in the southeastern part of the humongous Winter Circle, and it's called the Winter Triangle. The Winter Triangle consists of the stars Sirius, Procyon and Betelgeuse. It is an imaginary equilateral triangle drawn on the celestial sphere. Go outside and enjoy the show! Clear Skies Everyone!
