Moon phase and lunation details
5 days after Full Moon
Previous main lunar phase is the Full Moon before 5 days on 12 January 2017 at 11:34.
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 is entering ♎ Libra
Moon is passing first ∠0° of ♎ Libra tropical zodiac sector.
Apparent angular diameter ∠1814"
Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1814" and ∠1950".
Wolf Moon before 5 days
Next Full Moon is the Snow Moon of February 2017 after 24 days on 11 February 2017 at 00:33.
Upcoming main Moon phases
- Last Quarter in Libra ♎ on 19 January 2017 at 22:14
- New Moon in Aquarius ♒ on 28 January 2017 at 00:07
- First Quarter in Taurus ♉ on 4 February 2017 at 04:19

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 210 / 1163
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 210 of Meeus index or 1163 from Brown series.
Synodic month length 29.72 days
The length of the lunation is 29 days, 17 hours and 14 minutes. It is 2 hours and 23 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 4 hours and 30 minutes longer than the mean synodic month length. It is 2 hours and 33 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠223.4°
At the beginning of the lunation cycle the true anomaly is ∠223.4°. At the beginning of next synodic month the true anomaly is going to be ∠259.5°.
Moon before perigee
7 days after point of perigee on 10 January 2017 at 06:07 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next apogee on 22 January 2017 at 00:14 in ♐ Sagittarius.
Distance to Moon 395 044 km
The Moon is 395 044 km (245 469 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 404 913 km (251 601 mi).
Moon after ascending node
2 days after ascending node on 15 January 2017 at 10:45 in ♍ Virgo. The Moon is located north of the ecliptic over the following 12 days, until the lunar orbit crosses from North to South in descending node on 29 January 2017 at 22:21 in ♒ Aquarius.
Draconic month
2 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the beginning to the first part of the cycle.
Moon after northern standstill
6 days since the previous standstill on 11 January 2017 at 09:32 in ♋ Cancer when the Moon has reached North declination of ∠18.932°, the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-18.900° at the point of next southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn.
Syzygy in 10 days
In 10 days on 28 January 2017 at 00:07 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.
