Moon phase and lunation details
Moonrise and moonset
Moon rises at midnight and sets at noon. It is visible to the south in the morning.
Moon in ♊ Gemini
Moon is leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Apparent angular diameter ∠1829"
Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1829" and ∠1911".
Hunter Moon after 21 days
Next Full Moon is the Hunter Moon of October 2011 after 21 days on 12 October 2011 at 02:06.
Upcoming main Moon phases

Neap tide
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.
Lunation 144 / 1097
The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.
Synodic month length 29.34 days
The length of the 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 the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
Lunation length shorter than mean
The length of the current synodic month is 4 hours and 39 minutes shorter than the mean synodic month length. It is 1 hour and 30 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠333.4°
At the beginning of the lunation cycle the true anomaly is ∠333.4°. At the beginning of next synodic month the true anomaly is going to be ∠350.1°.
Moon after apogee
5 days after point of apogee on 15 September 2011 at 06:23 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.
Distance to Moon 391 800 km
The Moon is 391 800 km (243 453 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 556 km (222 175 mi).
Moon after descending node
1 day after descending node on 19 September 2011 at 19:38 in ♊ Gemini. The Moon is located south of the ecliptic over the following 11 days, until the lunar orbit crosses from South to North in ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius.
Draconic month
15 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.
Moon after northern standstill
1 day since the previous standstill on 19 September 2011 at 20:05 in ♊ Gemini when the Moon has reached North declination of ∠22.890°, the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-22.791° at the point of next southern standstill on 2 October 2011 at 11:38 in ♐ Sagittarius.
Syzygy in 6 days
In 6 days on 27 September 2011 at 11:09 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
