Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 20 September 2011 at 13:39.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♋ Cancer

Moon is passing about ∠22° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1875"

Lunar disc appears visually 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1875" and ∠1912".

Hunter Moon after 19 days

Next Full Moon is the Hunter Moon of October 2011 after 19 days on 12 October 2011 at 02:06.

Upcoming main Moon phases

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 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.34 days

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.

Lunation length shorter than mean

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.

Lunar orbit position on

True anomaly ∠333.4°

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°).

Moon before perigee

7 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 5 days, until it get to the point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 382 216 km

Moon is 382 216 km (237 498 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 357 556 km (222 175 mi).

Moon after descending node

2 days after its descending node on 19 September 2011 at 19:38 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 9 days, until it will cross the ecliptic from South to North in ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius.

Draconic month

17 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.

Moon after northern standstill

2 days after previous North standstill on 19 September 2011 at 20:05 in ♊ Gemini, when Moon has reached northern declination of ∠22.890°. Next 9 days the lunar orbit moves southward to face South declination of ∠-22.791° in the next southern standstill on 2 October 2011 at 11:38 in ♐ Sagittarius.

Syzygy in 4 days

After 4 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.
