Waning Crescent on . The illuminated surface of the moon is 27% and getting smaller. The lunar cycle is 24 days old.
The moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Main moon phases of the following lunar cycle.
Moon is passing first ∠1° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the Last Quarter before 2 days on 19 January 2017 at 22:14.
Next Full Moon is the Snow Moon of February 2017 after 19 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.
Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1949".
The Moon is 24 days old and navigating from the second to the final part of the current synodic month. This is lunation 210 of Meeus index or 1163 from Brown series.
The length of this lunation is 29 days, 17 hours and 14 minutes and it is 2 hours and 23 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
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.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠223.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠259.5°.
Moon is at apogee at 00:14 about 11 days since last perigee on 10 January 2017 at 06:07 in ♊ Gemini the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 15 days until point of next perigee on 6 February 2017 at 13:59 in ♊ Gemini.
This apogee Moon is 404 913 km (251 601 mi) away from Earth. It is 495 km further than the mean apogee distance, but it is still 1 796 km closer than the farthest apogee of 21st century.
7 days after ascending node on 15 January 2017 at 10:45 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 29 January 2017 at 22:21 in ♒ Aquarius.
11 days since the last northern 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 2 days to face maximum declination of ∠-18.900° at the point of next southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn.
7 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 5 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.
