Waxing Crescent on . The illuminated surface of the moon is 31% and growing larger. The lunar cycle is 5 days young.
The moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Main moon phases of the following lunar cycle.
Moon is passing about ∠5° of ♈ Aries tropical zodiac sector.
Previous main lunar phase is the New Moon before 5 days on 10 January 2100 at 12:55.
Next Full Moon is the Wolf Moon of January 2100 after 9 days on 26 January 2100 at 02:49.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1950".
The Moon is 5 days young and navigating from the beginning to the first part of the current synodic month. This is lunation 1237 of Meeus index or 2190 from Brown series.
The length of this lunation is 29 days, 15 hours and 59 minutes and it is 1 hour and 35 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 3 hours and 15 minutes longer than the mean synodic month length. It is 3 hours and 48 minutes shorter compared to 21st century's longest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠81.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠119.1°.
13 days since point of perigee on 3 January 2100 at 08:57 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 17 January 2100 at 10:48 in ♈ Aries.
The Moon is 405 157 km (251 753 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 420 km (251 295 mi).
1 day after ascending node on 15 January 2100 at 03:56 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 29 January 2100 at 00:35 in ♍ Virgo.
7 days since the last southern standstill on 8 January 2100 at 21:59 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.379° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.437° at the point of next northern standstill on 23 January 2100 at 08:16 in ♊ Gemini.
1 day since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 9 days on 26 January 2100 at 02:49 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
