Waning Gibbous on . The illuminated surface of the moon is 65% and getting smaller. The lunar cycle is 20 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 ∠19° of ♎ Libra tropical zodiac sector.
Previous main lunar phase is the Full Moon before 5 days on 21 January 2019 at 05:16.
Next Full Moon is the Snow Moon of February 2019 after 24 days on 19 February 2019 at 15:53.
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 1.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1924" and ∠1949".
The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 235 of Meeus index or 1188 from Brown series.
The length of this lunation is 29 days, 19 hours and 35 minutes and it is 35 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2019. 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 6 hours and 51 minutes longer than the mean synodic month length. It is 12 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 ∠149.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠175.6°.
4 days since point of perigee on 21 January 2019 at 19:58 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 5 February 2019 at 09:26 in ♒ Aquarius.
The Moon is 372 624 km (231 538 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 556 km (252 622 mi).
5 days after ascending node on 20 January 2019 at 22:48 in ♋ Cancer the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 3 February 2019 at 06:35 in ♑ Capricorn.
6 days since the last northern standstill on 19 January 2019 at 23:20 in ♋ Cancer when the Moon has reached North declination of ∠21.544° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-21.547° at the point of next southern standstill on 2 February 2019 at 00:48 in ♑ Capricorn.
5 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the beginning to the first part of the lunar cycle.
In 9 days on 4 February 2019 at 21:04 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.
