Moon phase and lunation details

3 days after New Moon

Previous main lunar phase is the New Moon before 3 days on 29 August 2011 at 03:04.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♎ Libra

Moon is leaving the last ∠4° of ♎ Libra tropical zodiac sector and will enter ♏ Scorpio later.

Apparent angular diameter ∠1972"

Lunar disc appears visually 3.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1901".

Harvest Moon after 10 days

Next Full Moon is the Harvest Moon of September 2011 after 10 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 4 days young. Earth's natural satellite is moving from the beginning to the first 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 after perigee

1 day 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 13 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 363 453 km

Moon is 363 453 km (225 839 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 406 068 km (252 319 mi).

Moon before ascending node

8 days after its descending node on 23 August 2011 at 17:23 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 3 days, until it will cross the ecliptic from South to North in ascending node on 5 September 2011 at 07:36 in ♐ Sagittarius.

Draconic month

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

Moon before southern standstill

8 days after previous North standstill on 23 August 2011 at 12:17 in ♊ Gemini, when Moon has reached northern declination of ∠23.149°. Next 3 days the lunar orbit moves southward to face South declination of ∠-23.047° in the next southern standstill on 5 September 2011 at 05:01 in ♐ Sagittarius.

Syzygy in 10 days

After 10 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.
