Previous main lunar phase is the Full Moon before 5 days on 11 January 2009 at 03:27.
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.
Moon is passing about ∠7° of ♎ Libra tropical zodiac sector.
Lunar disc appears visually 4.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1860" and ∠1950".
Next Full Moon is the Snow Moon of February 2009 after 24 days on 9 February 2009 at 14:49.
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 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 111 of Meeus index or 1064 from Brown series.
Length of current 111 lunation is 29 days, 19 hours and 33 minutes. This is the year's longest synodic month of 2009. It is 1 hour and 53 minutes longer than next lunation 112 length.
Length of current synodic month is 6 hours and 49 minutes longer than the mean length of synodic month, but it is still 14 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠186.6°. At the beginning of next synodic month true anomaly will be ∠213.2°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
6 days after point of perigee on 10 January 2009 at 10:52 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 23 January 2009 at 00:11 in ♑ Capricorn.
Moon is 385 298 km (239 413 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 406 116 km (252 349 mi).
4 days after its descending node on 12 January 2009 at 08:34 in ♌ Leo, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 26 January 2009 at 13:27 in ♒ Aquarius.
17 days after beginning of current draconic month in ♒ Aquarius, the Moon is moving from the second to the final part of it.
7 days after previous North standstill on 9 January 2009 at 05:38 in ♊ Gemini, when Moon has reached northern declination of ∠27.060°. Next 6 days the lunar orbit moves southward to face South declination of ∠-27.081° in the next southern standstill on 22 January 2009 at 14:02 in ♐ Sagittarius.
After 9 days on 26 January 2009 at 07:55 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
