Waning Gibbous on . The illuminated surface of the moon is 84% and getting smaller. The lunar cycle is 18 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 ♎ Libra tropical zodiac sector.
Previous main lunar phase is the Full Moon before 3 days on 28 January 2021 at 19:16.
Next Full Moon is the Snow Moon of February 2021 after 25 days on 27 February 2021 at 08:17.
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 0% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1947" and ∠1947".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 260 of Meeus index or 1213 from Brown series.
The length of this lunation is 29 days, 14 hours and 5 minutes and it is 1 hour and 10 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 21 minutes longer than the mean synodic month length. It is 5 hours and 42 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 ∠53.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠87°.
10 days since point of apogee on 21 January 2021 at 13:11 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 3 February 2021 at 19:33 in ♎ Libra.
The Moon is 368 165 km (228 767 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 370 127 km (229 986 mi).
7 days after ascending node on 24 January 2021 at 21:47 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 7 February 2021 at 00:29 in ♐ Sagittarius.
5 days since the last northern standstill on 26 January 2021 at 15:39 in ♋ Cancer when the Moon has reached North declination of ∠24.898° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-24.953° at the point of next southern standstill on 8 February 2021 at 15:34 in ♑ Capricorn.
7 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.
In 10 days on 11 February 2021 at 19:06 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.
