Previous main lunar phase is the First Quarter before 4 days on 16 August 2010 at 18:14.
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 ∠23° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1897".
Next Full Moon is the Sturgeon Moon of August 2010 after 3 days on 24 August 2010 at 17:05.
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 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.
Length of current 131 lunation is 29 days, 7 hours and 22 minutes. This is the year's shortest synodic month of 2010. It is 53 minutes shorter than next lunation 132 length.
Length of current synodic month is 5 hours and 22 minutes shorter than the mean length of synodic month, but it is still 47 minutes longer, compared to 21st century shortest.
This New Moon true anomaly is ∠349.5°. At beginning of next synodic month true anomaly will be ∠4.6°. 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°).
10 days after point of perigee on 10 August 2010 at 17:56 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 25 August 2010 at 05:51 in ♓ Pisces.
Moon is 399 568 km (248 280 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 406 390 km (252 519 mi).
1 day after its ascending node on 20 August 2010 at 12:13 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 13 days, until it will cross the ecliptic from North to South in descending node on 4 September 2010 at 00:16 in ♋ Cancer.
1 day after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the beginning to the first part of it.
2 days after previous South standstill on 18 August 2010 at 17:07 in ♐ Sagittarius, when Moon has reached southern declination of ∠-24.929°. Next 11 days the lunar orbit moves northward to face North declination of ∠24.807° in the next northern standstill on 2 September 2010 at 11:20 in ♊ Gemini.
After 3 days on 24 August 2010 at 17:05 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
