Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 8 January 2018 at 22:25.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♐ Sagittarius

Moon is passing about ∠14° of ♐ Sagittarius tropical zodiac sector.

Next Full Moon is the Wolf Moon of January 2018 after 18 days on 31 January 2018 at 13:27.

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 222 of Meeus index or 1175 from Brown series.

Synodic month length 29.82 days

The length of the lunation is 29 days, 19 hours and 47 minutes. This is the year's longest synodic month of 2018. It is 59 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 and it is the longest synodic month length of 21st century.

Lunar orbit position on

True anomaly ∠173.3°

At the beginning of the lunation cycle the true anomaly is ∠173.3°. At the beginning of next synodic month the true anomaly is going to be ∠198.1°.

Moon before perigee

11 days after point of perigee on 1 January 2018 at 21:54 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 day, until the Moon reaches the point of next apogee on 15 January 2018 at 02:10 in ♑ Capricorn.

Distance to Moon 403 751 km

The Moon is 403 751 km (250 879 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 461 km (252 563 mi).

Moon before descending node

9 days after ascending node on 4 January 2018 at 07:48 in ♌ Leo. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 18 January 2018 at 14:28 in ♒ Aquarius.

Draconic month

9 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

11 days since the previous standstill on 2 January 2018 at 00:01 in ♋ Cancer when the Moon has reached North declination of ∠20.055°, the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-20.048° at the point of next southern standstill on 15 January 2018 at 16:28 in ♑ Capricorn.

Syzygy in 3 days

In 3 days on 17 January 2018 at 02:17 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.
