Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 ∠19° of ♋ Cancer tropical zodiac sector.
Previous main lunar phase is the Full Moon before 1 day on 27 December 2099 at 12:58.
Next Full Moon is the Wolf Moon of January 2100 after 28 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 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1882" and ∠1951".
The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1236 of Meeus index or 2189 from Brown series.
The length of this lunation is 29 days, 13 hours and 47 minutes and it is 2 hours and 12 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 1 hour and 3 minutes longer than the mean synodic month length. It is 6 hours 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 ∠49.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠81.3°.
7 days since point of apogee on 20 December 2099 at 13:16 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 3 January 2100 at 08:57 in ♎ Libra.
The Moon is 380 819 km (236 630 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 370 356 km (230 129 mi).
9 days after ascending node on 19 December 2099 at 01:02 in ♓ Pisces 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 1 January 2100 at 21:13 in ♍ Virgo.
1 day since the last northern standstill on 26 December 2099 at 23:34 in ♊ Gemini when the Moon has reached North declination of ∠28.345° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-28.379° at the point of next southern standstill on 8 January 2100 at 21:59 in ♐ Sagittarius.
9 days 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 13 days on 10 January 2100 at 12:55 in ♑ Capricorn 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.
