January 3 and 4 – Quadrantid meteor shower
The Quadrantids are an above-average meteor shower, with frequencies of up to 40 meteors per hour at most. Quadrantids are believed to be formed from dust particles left behind by a dead comet called 2003 EH1, discovered in 2003. This meteor shower usually takes place between January 1 and 5 each year. This year’s peak will be on the night of the 3rd until dawn on the 4th. The first crescent moon of the month will set early, leaving the night sky perfect for this magnificent spectacle. The best viewing position is from a dark area after midnight. Meteor showers will radiate from the constellation Bouvier, but can appear anywhere in the night sky.

January 7 – Full moon
The Moon will appear opposite the Sun when viewed from Earth and its surface will be fully illuminated. This phase occurred at 6:09 a.m. This full moon was known to early Native American tribes as the Wolf Moon because it was the time when hungry wolves howled loudly outside their camps. This Full Moon is also known as the Old Moon and the After-Christmas Moon.
January 22 – New Moon
The Moon will be on the same side as the Sun when viewed from Earth and will not appear in the night sky. This phase occurred at 3:55 p.m. This is the best time of the month to observe faint objects such as galaxies or star clusters, as they will not be affected by moonlight.
January 30 – Mercury reaches maximum western elongation
Mercury reaches an elongated position to the west, up to 25 degrees from the Sun. The best time to view Mercury is when it is highest on the horizon in the morning. Look for the planet in the eastern sky before dawn.
