Waxing Gibbous on . The illuminated surface of the moon is 76% and growing larger. The lunar cycle is 10 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is passing about ∠19° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the First Quarter before 2 days on 4 February 2017 at 04:19.
Next Full Moon is the Snow Moon of February 2017 after 4 days on 11 February 2017 at 00:33.
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.
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1945".
The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 211 of Meeus index or 1164 from Brown series.
The length of this lunation is 29 days, 14 hours and 51 minutes and it is 2 hours and 52 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 2 hours and 7 minutes longer than the mean synodic month length. It is 4 hours and 56 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 ∠259.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠295°.
Moon is at perigee at 13:59 about 15 days since last apogee on 22 January 2017 at 00:14 in ♐ Sagittarius the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 12 days until point of next apogee on 18 February 2017 at 21:14 in ♏ Scorpio.
This perigee Moon is 368 817 km (229 172 mi) away from Earth. It is 6 309 km closer than the mean perigee distance, but it is still 1 539 km further than the closest perigee of 21st century.
7 days after descending node on 29 January 2017 at 22:21 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 February 2017 at 19:49 in ♌ Leo.
12 days since the last southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn when the Moon has reached South declination of ∠-18.900° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.865° at the point of next northern standstill on 7 February 2017 at 18:34 in ♊ Gemini.
22 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.
In 4 days on 11 February 2017 at 00:33 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
