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 221 / 1174
The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 221 of Meeus index or 1174 from Brown series.
Synodic month length 29.78 days
The length of the lunation is 29 days, 18 hours and 48 minutes. It is 59 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
Lunation length longer than mean
The length of the current synodic month is 6 hours and 4 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 ∠147°
At the beginning of the lunation cycle the true anomaly is ∠147°. At the beginning of next synodic month the true anomaly is going to be ∠173.3°.
Moon after perigee
6 days after point of perigee on 4 December 2017 at 08:42 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 8 days, until the Moon reaches the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.
Distance to Moon 378 668 km
The Moon is 378 668 km (235 293 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 406 605 km (252 653 mi).
Moon after ascending node
2 days after ascending node on 8 December 2017 at 00:39 in ♌ Leo. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 22 December 2017 at 10:04 in ♒ Aquarius.
Draconic month
2 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 after northern standstill
5 days since the previous standstill on 5 December 2017 at 11:43 in ♋ Cancer when the Moon has reached North declination of ∠20.015°, the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-20.062° at the point of next southern standstill on 19 December 2017 at 09:31 in ♑ Capricorn.
Syzygy in 7 days
In 7 days on 18 December 2017 at 06:31 in ♐ Sagittarius 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.
