Moon phase and lunation details

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 4 September 2011 at 17:39.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon is entering ♒ Aquarius

Moon is passing first ∠1° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1846"

Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1846" and ∠1905".

Harvest Moon after 3 days

Next Full Moon is the Harvest Moon of September 2011 after 3 days on 12 September 2011 at 09:27.

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 11 days young. Earth's natural satellite is moving from the first to the middle 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 apogee

8 days after point of perigee on 30 August 2011 at 17:35 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 15 September 2011 at 06:23 in ♈ Aries.

Previous perigeeNext apogee

Distance to Moon 388 204 km

Moon is 388 204 km (241 219 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 406 068 km (252 319 mi).

Moon after ascending node

3 days after its ascending node on 5 September 2011 at 07:36 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 19 September 2011 at 19:38 in ♊ Gemini.

Draconic month

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

Moon after southern standstill

3 days after previous South standstill on 5 September 2011 at 05:01 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.047°. Next 11 days the lunar orbit moves northward to face North declination of ∠22.890° in the next northern standstill on 19 September 2011 at 20:05 in ♊ Gemini.

Syzygy in 3 days

After 3 days on 12 September 2011 at 09:27 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
