Waning Gibbous on . The illuminated surface of the moon is 81% 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 ∠2° of ♎ Libra tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 25 January 2024 at 17:54.
Next Full Moon is the Snow Moon of February 2024 after 25 days on 24 February 2024 at 12:30.
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 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1948".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 297 of Meeus index or 1250 from Brown series.
The length of this lunation is 29 days, 11 hours and 2 minutes and it is 1 hour and 1 minute 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 1 hour and 42 minutes shorter than the mean synodic month length. It is 4 hours and 27 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 ∠328° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠345.9°.
1 day since point of apogee on 29 January 2024 at 08:14 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 10 February 2024 at 18:49 in ♒ Aquarius.
The Moon is 404 369 km (251 263 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 358 088 km (222 506 mi).
12 days after ascending node on 17 January 2024 at 14:05 in ♈ Aries the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 31 January 2024 at 20:17 in ♎ Libra.
7 days since the last northern standstill on 23 January 2024 at 03:44 in ♋ Cancer when the Moon has reached North declination of ∠28.203° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-28.304° at the point of next southern standstill on 6 February 2024 at 17:06 in ♐ Sagittarius.
12 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 9 February 2024 at 22:59 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.
