Waning Gibbous on . The illuminated surface of the moon is 97% and getting smaller. The lunar cycle is 16 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠8° of ♌ Leo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 7 January 2099 at 01:50.
Next Full Moon is the Snow Moon of February 2099 after 28 days on 5 February 2099 at 12:48.
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 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1951".
The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1224 of Meeus index or 2177 from Brown series.
The length of this lunation is 29 days, 17 hours and 43 minutes and it is 1 hour and 15 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 4 hours and 59 minutes longer than the mean synodic month length. It is 2 hours and 4 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 ∠115.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149°.
Moon is at perigee at 18:21 about 11 days since last apogee on 27 December 2098 at 21:01 in ♒ Aquarius the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 16 days until point of next apogee on 24 January 2099 at 12:47 in ♓ Pisces.
This perigee Moon is 361 107 km (224 381 mi) away from Earth. It is 1 401 km closer than the mean perigee distance, but it is still 9 249 km further than the closest perigee of 21st century.
8 days after ascending node on 30 December 2098 at 20:34 in ♈ Aries the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 12 January 2099 at 15:35 in ♎ Libra.
2 days since the last northern standstill on 6 January 2099 at 00:46 in ♋ Cancer when the Moon has reached North declination of ∠28.354° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-28.389° at the point of next southern standstill on 18 January 2099 at 22:15 in ♐ Sagittarius.
8 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.
In 12 days on 21 January 2099 at 09:07 in ♒ Aquarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
