Previous main lunar phase is the Full Moon before 7 days on 12 September 2011 at 09:27.
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 ∠14° of ♊ Gemini tropical zodiac sector.
Lunar disc appears visually 5.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1810" and ∠1910".
Next Full Moon is the Hunter Moon of October 2011 after 22 days on 12 October 2011 at 02:06.
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 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.
Length of current 144 lunation is 29 days, 8 hours and 5 minutes. This is the year's shortest synodic month of 2011. It is 42 minutes shorter than next lunation 145 length.
Length of current synodic month is 4 hours and 39 minutes shorter than the mean length of synodic month, but it is still 1 hour and 30 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠333.4°. At the beginning of next synodic month true anomaly will be ∠350.1°. 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 apogee on 15 September 2011 at 06:23 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.
Moon is 396 030 km (246 082 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 357 556 km (222 175 mi).
Moon is in descending node in ♊ Gemini at 19:38 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 12 days to meet ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius.
14 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
At 20:05 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠22.890°. Next 12 days the lunar orbit will move in opposite southward direction to face South declination of ∠-22.791° in its southern standstill point on 2 October 2011 at 11:38 in ♐ Sagittarius.
After 7 days on 27 September 2011 at 11:09 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
