Quarter ♏ Scorpio
Last Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 54% and getting smaller. The 21 days old Moon is in ♎ Libra.
* The exact date and time of this Last Quarter phase is on 19 January 2017 at 22:14 UTC.
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon is passing about ∠25° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 8.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1784" and ∠1950".
Next Full Moon is the Snow Moon of February 2017 after 22 days on 11 February 2017 at 00:33.
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.
The Moon is 21 days old. Earth's natural satellite is moving through the last 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°).
9 days after point of perigee on 10 January 2017 at 06:07 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 2 days, until it get to the point of next apogee on 22 January 2017 at 00:14 in ♐ Sagittarius.
Moon is 401 889 km (249 722 mi) away from Earth on this date. Moon moves farther next 2 days until apogee, when Earth-Moon distance will reach 404 913 km (251 601 mi).
4 days after its ascending node on 15 January 2017 at 10:45 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 29 January 2017 at 22:21 in ♒ Aquarius.
4 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.
8 days after previous North standstill on 11 January 2017 at 09:32 in ♋ Cancer, when Moon has reached northern declination of ∠18.932°. Next 5 days the lunar orbit moves southward to face South declination of ∠-18.900° in the next southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn.
After 8 days on 28 January 2017 at 00:07 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
