Previous main lunar phase is the Full Moon before 2 days on 21 August 2013 at 01:45.
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 first ∠3° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1881" and ∠1898".
Next Full Moon is the Harvest Moon of September 2013 after 26 days on 19 September 2013 at 11:13.
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 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.
Length of current 168 lunation is 29 days, 13 hours and 45 minutes. It is 47 minutes longer than next lunation 169 length.
Length of current synodic month is 1 hour and 1 minute longer than the mean length of synodic month, but it is still 6 hours and 2 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠216.9°. At the beginning of next synodic month true anomaly will be ∠249.2°. 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°).
4 days after point of perigee on 19 August 2013 at 01:26 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 7 days, until it get to the point of next apogee on 30 August 2013 at 23:46 in ♋ Cancer.
Moon is 380 991 km (236 737 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 404 883 km (251 583 mi).
9 days after its ascending node on 13 August 2013 at 16:20 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 26 August 2013 at 08:19 in ♉ Taurus.
9 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
6 days after previous South standstill on 16 August 2013 at 12:06 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.906°. Next 6 days the lunar orbit moves northward to face North declination of ∠19.801° in the next northern standstill on 29 August 2013 at 17:03 in ♊ Gemini.
After 12 days on 5 September 2013 at 11:36 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
