Waning Gibbous on . The illuminated surface of the moon is 85% 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 about ∠25° of ♍ Virgo tropical zodiac sector.
Previous main lunar phase is the Full Moon before 3 days on 26 January 2100 at 02:49.
Next Full Moon is the Snow Moon of February 2100 after 26 days on 24 February 2100 at 14:51.
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 0.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1948".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1237 of Meeus index or 2190 from Brown series.
The length of this lunation is 29 days, 15 hours and 59 minutes and it is 1 hour and 35 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 3 hours and 15 minutes longer than the mean synodic month length. It is 3 hours and 48 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 ∠81.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠119.1°.
Moon is at perigee at 05:53 about 11 days since last apogee on 17 January 2100 at 10:48 in ♈ Aries the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 14 February 2100 at 06:46 in ♈ Aries.
This perigee Moon is 366 241 km (227 572 mi) away from Earth. It is 3 733 km closer than the mean perigee distance, but it is still 4 115 km further than the closest perigee of 21st century.
Moon is in descending node in ♍ Virgo at 00:35 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 11 February 2100 at 09:33 in ♓ Pisces.
6 days since the last northern standstill on 23 January 2100 at 08:16 in ♊ Gemini when the Moon has reached North declination of ∠28.437° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-28.496° at the point of next southern standstill on 5 February 2100 at 04:00 in ♐ Sagittarius.
14 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.
In 10 days on 9 February 2100 at 04:55 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.
