* The exact date and time of this First Quarter phase is on 5 January 2017 at 19:47 UTC.
Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.
Moon is passing about ∠11° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 0.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1944" and ∠1951".
Next Full Moon is the Wolf Moon of January 2017 after 6 days on 12 January 2017 at 11:34.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 210 of Meeus index or 1163 from Brown series.
Length of current 210 lunation is 29 days, 17 hours and 14 minutes. It is 2 hours and 23 minutes longer than next lunation 211 length.
Length of current synodic month is 4 hours and 30 minutes longer than the mean length of synodic month, but it is still 2 hours and 33 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠223.4°. At the beginning of next synodic month true anomaly will be ∠259.5°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
11 days after point of apogee on 25 December 2016 at 05:55 in ♏ Scorpio. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 10 January 2017 at 06:07 in ♊ Gemini.
Moon is 368 704 km (229 102 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 363 242 km (225 708 mi).
2 days after its descending node on 2 January 2017 at 18:14 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 15 January 2017 at 10:45 in ♍ Virgo.
17 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the second to the final part of it.
7 days after previous South standstill on 29 December 2016 at 03:30 in ♑ Capricorn, when Moon has reached southern declination of ∠-18.958°. Next 5 days the lunar orbit moves northward to face North declination of ∠18.932° in the next northern standstill on 11 January 2017 at 09:32 in ♋ Cancer.
After 6 days on 12 January 2017 at 11:34 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
