Previous main lunar phase is the Last Quarter before 1 day on 3 February 2013 at 13:56.
Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1968" and ∠1946".
Next Full Moon is the Snow Moon of February 2013 after 21 days on 25 February 2013 at 20:26.
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 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 161 of Meeus index or 1114 from Brown series.
Length of current 161 lunation is 29 days, 11 hours and 36 minutes. It is 55 minutes shorter than next lunation 162 length.
Length of current synodic month is 1 hour and 8 minutes shorter than the mean length of synodic month, but it is still 5 hours and 1 minute longer, compared to 21st century shortest.
This New Moon true anomaly is ∠23.3°. At beginning of next synodic month true anomaly will be ∠44.2°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
13 days after point of apogee on 22 January 2013 at 10:52 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 7 February 2013 at 12:09 in ♑ Capricorn.
Moon is 364 242 km (226 329 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 365 314 km (226 996 mi).
Moon is in ascending node in ♏ Scorpio at 02:14 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 12 days to meet descending node on 17 February 2013 at 02:57 in ♉ Taurus.
At 02:14 on this date the Moon is completing its previous draconic month and is entering the new one.
12 days after previous North standstill on 23 January 2013 at 05:12 in ♊ Gemini, when Moon has reached northern declination of ∠20.816°. Next day the lunar orbit moves southward to face South declination of ∠-20.704° in the next southern standstill on 6 February 2013 at 00:27 in ♐ Sagittarius.
After 5 days on 10 February 2013 at 07:20 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
