Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 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 leaving the last ∠1° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.
Previous main lunar phase is the Full Moon before 1 day on 30 January 2010 at 06:18.
Next Full Moon is the Snow Moon of February 2010 after 28 days on 28 February 2010 at 16:38.
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 ∠1970" and ∠1947".
The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 124 of Meeus index or 1077 from Brown series.
The length of this lunation is 29 days, 19 hours and 40 minutes and it is 1 hour and 30 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2010. 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 6 hours and 56 minutes longer than the mean synodic month length. It is 7 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 ∠164.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠188.9°.
1 day since point of perigee on 30 January 2010 at 09:03 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 13 February 2010 at 02:06 in ♒ Aquarius.
The Moon is 363 935 km (226 139 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 406 542 km (252 613 mi).
2 days after descending node on 29 January 2010 at 00:02 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 February 2010 at 04:58 in ♑ Capricorn.
4 days since the last northern standstill on 26 January 2010 at 21:04 in ♊ Gemini when the Moon has reached North declination of ∠25.783° the lunar orbit is extending southward over the next 8 days to face maximum declination of ∠-25.749° at the point of next southern standstill on 8 February 2010 at 14:27 in ♐ Sagittarius.
16 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.
In 13 days on 14 February 2010 at 02:51 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.
