Waning Crescent on . The illuminated surface of the moon is 17% and getting smaller. The lunar cycle is 25 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing first ∠0° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 3 days on 6 January 2021 at 09:37.
Next Full Moon is the Wolf Moon of January 2021 after 19 days on 28 January 2021 at 19:16.
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 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1951".
The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.
The length of this lunation is 29 days, 12 hours and 44 minutes and it is 1 hour and 21 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 equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠30.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠53.8°.
Moon is at perigee at 15:39 about 15 days since last apogee on 24 December 2020 at 16:32 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 12 days until point of next apogee on 21 January 2021 at 13:11 in ♉ Taurus.
This perigee Moon is 367 390 km (228 286 mi) away from Earth. It is 4 882 km closer than the mean perigee distance, but it is still 2 966 km further than the closest perigee of 21st century.
11 days after ascending node on 28 December 2020 at 15:03 in ♊ Gemini 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 10 January 2021 at 20:15 in ♐ Sagittarius.
10 days since the last northern standstill on 30 December 2020 at 07:53 in ♋ Cancer when the Moon has reached North declination of ∠24.868° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-24.870° at the point of next southern standstill on 12 January 2021 at 08:18 in ♑ Capricorn.
11 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 3 days on 13 January 2021 at 05:00 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.
