Waning Gibbous on . The illuminated surface of the moon is 82% and getting smaller. The lunar cycle is 19 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 first ∠0° of ♍ Virgo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 27 December 2023 at 00:33.
Next Full Moon is the Wolf Moon of January 2024 after 25 days on 25 January 2024 at 17:54.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1951".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 296 of Meeus index or 1249 from Brown series.
The length of this lunation is 29 days, 12 hours and 25 minutes and it is 1 hour and 23 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 19 minutes shorter than the mean synodic month length. It is 5 hours and 50 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠303.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠328°.
14 days since point of perigee on 16 December 2023 at 18:53 in ♒ Aquarius 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 1 January 2024 at 15:28 in ♍ Virgo.
The Moon is 405 126 km (251 734 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 911 km (251 600 mi).
9 days after ascending node on 21 December 2023 at 13:54 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 4 January 2024 at 18:52 in ♎ Libra.
4 days since the last northern standstill on 26 December 2023 at 21:50 in ♊ Gemini when the Moon has reached North declination of ∠28.131° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-28.164° at the point of next southern standstill on 10 January 2024 at 07:04 in ♑ Capricorn.
9 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 10 days on 11 January 2024 at 11:57 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.
