Moon phase and lunation details
4 days after Full Moon
Previous main lunar phase is the Full Moon before 4 days on 12 October 2011 at 02:06.
Moonrise and moonset
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 in ♊ Gemini
Moon is passing about ∠11° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1801"
Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1925".
Hunter Moon before 4 days
Next Full Moon is the Beaver Moon of November 2011 after 25 days on 10 November 2011 at 20:16.
Upcoming main Moon phases
- Last Quarter in Cancer ♋ on 20 October 2011 at 03:30
- New Moon in Libra ♎ on 26 October 2011 at 19:56
- First Quarter in Aquarius ♒ on 2 November 2011 at 16:38

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 145 / 1098
The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 145 of Meeus index or 1098 from Brown series.
Synodic month length 29.37 days
The length of the lunation is 29 days, 8 hours and 47 minutes. It is 1 hour and 27 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
Lunation length shorter than mean
The length of the current synodic month is 3 hours and 57 minutes shorter than the mean synodic month length. It is 2 hours and 12 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠350.1°
At the beginning of the lunation cycle the true anomaly is ∠350.1°. At the beginning of next synodic month the true anomaly is going to be ∠5.3°.
Moon after apogee
4 days after point of apogee on 12 October 2011 at 11:43 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 26 October 2011 at 12:26 in ♎ Libra.
Distance to Moon 398 045 km
The Moon is 398 045 km (247 334 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 357 051 km (221 861 mi).
Moon in descending node
Moon is in descending node in ♊ Gemini at 21:01 crossing the ecliptic from North to South to meet ascending node 13 days later on 29 October 2011 at 14:59 in ♐ Sagittarius.
Draconic month
14 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 before northern standstill
14 days since the previous standstill on 2 October 2011 at 11:38 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.791°, the lunar orbit is extending northward over the next day to face maximum declination of ∠22.665° at the point of next northern standstill on 17 October 2011 at 02:06 in ♊ Gemini.
Syzygy in 10 days
In 10 days on 26 October 2011 at 19:56 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.
