Moon phase and lunation details
Moonrise and moonset
Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.
Moon in ♌ Leo
Moon is passing about ∠11° of ♌ Leo tropical zodiac sector.
Apparent angular diameter ∠1958"
Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1958" and ∠1947".

Upcoming main Moon phases
- Last Quarter in Scorpio ♏ on 7 February 2018 at 15:54
- New Moon in Aquarius ♒ on 15 February 2018 at 21:05
- First Quarter in Gemini ♊ on 23 February 2018 at 08:09

Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 223 / 1176
The Moon is 14 days old. Earth's natural satellite is moving through the middle 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
1 day 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 11 days, until the Moon reaches the point of next apogee on 11 February 2018 at 14:16 in ♐ Sagittarius.
Distance to Moon 366 054 km
The Moon is 366 054 km (227 455 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 701 km (252 091 mi).
Moon in ascending node
Moon is in ascending node in ♌ Leo at 18:46 crossing the ecliptic from South to North to meet descending node 14 days later on 14 February 2018 at 21:11 in ♒ Aquarius.
New draconic month
At 18:46 the Moon completes the previous draconic month and enters the new one.
Moon after northern standstill
2 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 11 days to face maximum declination of ∠-20.026° at the point of next southern standstill on 11 February 2018 at 23:21 in ♑ Capricorn.
Sun-Earth-Moon syzygy
The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
