Previous main lunar phase is the First Quarter before 2 days on 11 February 2011 at 07:18.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing about ∠20° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1861" and ∠1943".
Next Full Moon is the Snow Moon of February 2011 after 4 days on 18 February 2011 at 08:36.
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 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.
Length of current 137 lunation is 29 days, 18 hours and 15 minutes. This is the year's longest synodic month of 2011. It is 29 minutes longer than next lunation 138 length.
Length of current synodic month is 5 hours and 31 minutes longer than the mean length of synodic month, but it is still 1 hour and 32 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠139.2°. At beginning of next synodic month true anomaly will be ∠167°. 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°).
6 days after point of apogee on 6 February 2011 at 23:13 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 19 February 2011 at 07:27 in ♍ Virgo.
Moon is 385 197 km (239 350 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 247 km (222 604 mi).
13 days after its ascending node on 30 January 2011 at 18:29 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 14 February 2011 at 08:14 in ♋ Cancer.
13 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the first to the middle part of it.
At 09:00 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠24.080°. Next 12 days the lunar orbit will move in opposite southward direction to face South declination of ∠-23.985° in its southern standstill point on 25 February 2011 at 22:13 in ♐ Sagittarius.
After 4 days on 18 February 2011 at 08:36 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
