4 days after Full Moon
Previous main lunar phase is the Full Moon before 4 days on 31 January 2018 at 13:27.
Moonrise and moonset
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.
Moon in ♎ Libra
Moon is passing about ∠21° of ♎ Libra tropical zodiac sector.
Apparent angular diameter ∠1851"
Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1851" and ∠1946".

Neap tide
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.
Lunation 223 / 1176
The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 223 of Meeus index or 1176 from Brown series.
Synodic month length 29.78 days
The length of the lunation is 29 days, 18 hours and 48 minutes. This is the year's longest synodic month of 2018. It is 2 hours and 42 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
Lunation length longer than mean
The length of the current synodic month is 7 hours and 3 minutes longer than the mean synodic month length. It is 59 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠198.1°
At the beginning of the lunation cycle the true anomaly is ∠198.1°. At the beginning of next synodic month the true anomaly is going to be ∠227.1°.
Moon after perigee
6 days after point of perigee on 30 January 2018 at 09:54 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 6 days, until the Moon reaches the point of next apogee on 11 February 2018 at 14:16 in ♐ Sagittarius.
Distance to Moon 387 291 km
The Moon is 387 291 km (240 651 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 405 701 km (252 091 mi).
Moon after ascending node
4 days after ascending node on 31 January 2018 at 18:46 in ♌ Leo. The Moon is located north of the ecliptic over the following 9 days, until the lunar orbit crosses from North to South in descending node on 14 February 2018 at 21:11 in ♒ Aquarius.
Draconic month
4 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the beginning to the first part of the cycle.
Moon before southern standstill
7 days since the previous standstill on 29 January 2018 at 11:32 in ♋ Cancer when the Moon has reached North declination of ∠20.027°, the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-20.026° at the point of next southern standstill on 11 February 2018 at 23:21 in ♑ Capricorn.
Syzygy in 10 days
In 10 days on 15 February 2018 at 21:05 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.
