Upcoming main Moon phases
- Last Quarter in Virgo ♍ on 10 December 2017 at 07:51
- New Moon in Sagittarius ♐ on 18 December 2017 at 06:31
- First Quarter in Aries ♈ on 26 December 2017 at 09:20

Moderate tide
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
Lunation 221 / 1174
The Moon is 15 days old. Earth's natural satellite is moving from the middle to 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
Length of current 221 lunation is 29 days, 18 hours and 48 minutes. It is 59 minutes shorter than next lunation 222 length.
Lunation length longer than mean
Length of current synodic month is 6 hours and 4 minutes longer than the mean length of synodic month, but it is still 59 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠147°
This New Moon true anomaly is ∠147°. At beginning of next synodic month true anomaly will be ∠173.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon in perigee
Moon is reaching point of perigee on this date at 08:42, this is 12 days after last apogee on 21 November 2017 at 18:52 in ♐ Sagittarius. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 14 days ahead, until it will get to the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.
Distance to Moon 357 496 km
This perigee Moon is 357 496 km (222 138 mi) away from Earth. It is 5 012 km closer than the mean perigee distance, but it is still 12 860 km farther than the closest perigee of 21st century.
Moon before ascending node
9 days after its descending node on 25 November 2017 at 08:22 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 8 December 2017 at 00:39 in ♌ Leo.
Draconic month
23 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the second to the final part of it.
Moon before northern standstill
12 days after previous South standstill on 22 November 2017 at 02:06 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.959°. Next day the lunar orbit moves northward to face North declination of ∠20.015° in the next northern standstill on 5 December 2017 at 11:43 in ♋ Cancer.
Syzygy in 13 days
After 13 days on 18 December 2017 at 06:31 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
