Waning Gibbous on . The illuminated surface of the moon is 83% and getting smaller. The lunar cycle is 18 days old.
The moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Main moon phases of the following lunar cycle.
Moon is passing about ∠9° of ♎ Libra tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 3 February 2015 at 23:09.
Next Full Moon is the Worm Moon of March 2015 after 25 days on 5 March 2015 at 18:06.
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 8.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1781" and ∠1945".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 186 of Meeus index or 1139 from Brown series.
The length of this lunation is 29 days, 10 hours and 34 minutes and it is 45 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 10 minutes shorter than the mean synodic month length. It is 3 hours and 59 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠338.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠354.5°.
2 days since point of apogee on 6 February 2015 at 06:25 in ♍ Virgo the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 19 February 2015 at 07:29 in ♓ Pisces.
The Moon is 402 460 km (250 077 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 356 992 km (221 825 mi).
Moon is in ascending node in ♎ Libra at 17:10 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 21 February 2015 at 16:05 in ♈ Aries.
8 days since the last northern standstill on 31 January 2015 at 00:59 in ♋ Cancer when the Moon has reached North declination of ∠18.513° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-18.402° at the point of next southern standstill on 14 February 2015 at 17:17 in ♐ Sagittarius.
At 17:10 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.
In 10 days on 18 February 2015 at 23:47 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.
