Waning Crescent on . The illuminated surface of the moon is 3% and getting smaller. The lunar cycle is 27 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 leaving the last ∠1° of ♑ Capricorn tropical zodiac sector and will enter ♒ Aquarius later.
Previous main lunar phase is the Last Quarter before 5 days on 1 February 2100 at 21:16.
Next Full Moon is the Snow Moon of February 2100 after 17 days on 24 February 2100 at 14:51.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1848" and ∠1945".
The Moon is 27 days old and navigating from the second to the final 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°.
9 days since point of perigee on 29 January 2100 at 05:53 in ♍ Virgo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 14 February 2100 at 06:46 in ♈ Aries.
The Moon is 387 837 km (240 991 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 405 204 km (251 782 mi).
9 days after descending node on 29 January 2100 at 00:35 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 February 2100 at 09:33 in ♓ Pisces.
2 days since the last southern standstill on 5 February 2100 at 04:00 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.496° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠28.552° at the point of next northern standstill on 19 February 2100 at 17:35 in ♊ Gemini.
23 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 1 day 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.
