Previous main lunar phase is the Full Moon before 1 day on 19 September 2013 at 11:13.
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 ∠11° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 2.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1872" and ∠1911".
Next Full Moon is the Hunter Moon of October 2013 after 28 days on 18 October 2013 at 23:38.
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 169 of Meeus index or 1122 from Brown series.
Length of current 169 lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer than next lunation 170 length.
Length of current synodic month is 14 minutes longer than the mean length of synodic month, but it is still 6 hours and 49 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠249.2°. At the beginning of next synodic month true anomaly will be ∠285.3°. 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 15 September 2013 at 16:34 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 27 September 2013 at 18:17 in ♋ Cancer.
Moon is 382 962 km (237 962 mi) away from Earth on this date. Moon moves farther next 7 days until apogee, when Earth-Moon distance will reach 404 309 km (251 226 mi).
10 days after its ascending node on 9 September 2013 at 17:29 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 22 September 2013 at 13:48 in ♉ Taurus.
10 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
7 days after previous South standstill on 12 September 2013 at 18:30 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.685°. Next 5 days the lunar orbit moves northward to face North declination of ∠19.599° in the next northern standstill on 26 September 2013 at 01:03 in ♊ Gemini.
After 14 days on 5 October 2013 at 00:35 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
