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".

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
Length of current 145 lunation is 29 days, 8 hours and 47 minutes. It is 1 hour and 27 minutes shorter than next lunation 146 length.
Lunation length shorter than mean
Length of current synodic month is 3 hours and 57 minutes shorter than the mean length of synodic month, but it is still 2 hours and 12 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠350.1°
This New Moon true anomaly is ∠350.1°. At beginning of next synodic month true anomaly will be ∠5.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon after apogee
4 days after point of apogee on 12 October 2011 at 11:43 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 26 October 2011 at 12:26 in ♎ Libra.
Distance to Moon 398 045 km
Moon is 398 045 km (247 334 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 357 051 km (221 861 mi).
Moon in descending node
Moon is in descending node in ♊ Gemini at 21:01 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 29 October 2011 at 14:59 in ♐ Sagittarius.
Draconic month
14 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
Moon before northern standstill
14 days after previous South standstill on 2 October 2011 at 11:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-22.791°. Next day the lunar orbit moves northward to face North declination of ∠22.665° in the next northern standstill on 17 October 2011 at 02:06 in ♊ Gemini.
Syzygy in 10 days
After 10 days on 26 October 2011 at 19:56 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
