Previous main lunar phase is the Full Moon before 1 day on 30 January 2010 at 06:18.
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.
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1947".
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.
The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 124 of Meeus index or 1077 from Brown series.
Length of current 124 lunation is 29 days, 19 hours and 40 minutes. This is the year's longest synodic month of 2010. It is 1 hour and 30 minutes longer than next lunation 125 length.
Length of current synodic month is 6 hours and 56 minutes longer than the mean length of synodic month, but it is still 7 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠164.3°. At the beginning of next synodic month true anomaly will be ∠188.9°. 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°).
1 day after point of perigee on 30 January 2010 at 09:03 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 13 February 2010 at 02:06 in ♒ Aquarius.
Moon is 363 935 km (226 139 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 406 542 km (252 613 mi).
2 days after its descending node on 29 January 2010 at 00:02 in ♋ Cancer, 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 11 February 2010 at 04:58 in ♑ Capricorn.
16 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the second to the final part of it.
4 days after previous North standstill on 26 January 2010 at 21:04 in ♊ Gemini, when Moon has reached northern declination of ∠25.783°. Next 8 days the lunar orbit moves southward to face South declination of ∠-25.749° in the next southern standstill on 8 February 2010 at 14:27 in ♐ Sagittarius.
After 13 days on 14 February 2010 at 02:51 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
