Winter Solstice. The Sun reaches its furthest southern point marking the beginning of winter in the northern hemisphere and summer in the southern. This is also the longest night & the shortest day in the northern hemisphere - opposite in the south.
Mon 22 Dec 8:00 PM
The Moon is at perigee, subtending an angular size of 33' 21" at a distance of 358,337 km (222,660 miles). Larger tides will result.
Tue 23 Dec 8:00 AM
The peak of the Ursid meteor shower. With its radiant in Ursa Minor, the Ursids are visible from the entire northern hemisphere. The meteors may be associated with comet Tuttle, but there are enough differences between their orbits that the meteors are probably an ancient product of the comet. This shower averages between 10 and 50 meteors per hour and most are quite faint. The new moon will aid in observation this year, the best of which will be between local midnight and dawn.
Tue 23 Dec 5:43 PM
New Moon, start of lunation 1002.
Wed 24 Dec
Mercury is at perihelion.
