Waning Gibbous on . The illuminated surface of the moon is 81% and getting smaller. The lunar cycle is 19 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 leaving the last ∠4° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.
Previous main lunar phase is the Full Moon before 3 days on 22 December 2018 at 17:49.
Next Full Moon is the Wolf Moon of January 2019 after 25 days on 21 January 2019 at 05:16.
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 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1951".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 234 of Meeus index or 1187 from Brown series.
The length of this lunation is 29 days, 18 hours and 8 minutes and it is 1 hour and 27 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 5 hours and 24 minutes longer than the mean synodic month length. It is 1 hour and 39 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 ∠116.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149.4°.
2 days since point of perigee on 24 December 2018 at 09:52 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 9 January 2019 at 04:29 in ♒ Aquarius.
The Moon is 363 582 km (225 919 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 116 km (252 349 mi).
2 days after ascending node on 24 December 2018 at 11:54 in ♋ Cancer the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 7 January 2019 at 00:08 in ♒ Aquarius.
3 days since the last northern standstill on 23 December 2018 at 11:48 in ♋ Cancer when the Moon has reached North declination of ∠21.550° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-21.553° at the point of next southern standstill on 5 January 2019 at 18:45 in ♑ Capricorn.
2 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 10 days on 6 January 2019 at 01:28 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.
