Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 13 August 2009 at 18:55.

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 leaving the last ∠1° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1973"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1896".

Harvest Moon after 17 days

Next Full Moon is the Harvest Moon of September 2009 after 17 days on 4 September 2009 at 16:03.

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 118 / 1071

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 118 of Meeus index or 1071 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 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 5 hours and 17 minutes shorter than the mean synodic month length. It is 52 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠4.5°

At the beginning of the lunation cycle the true anomaly is ∠4.5°. At the beginning of next synodic month the true anomaly is going to be ∠20.3°.

Moon before apogee

14 days after point of apogee on 4 August 2009 at 00:42 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 363 350 km

The Moon is 363 350 km (225 775 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 359 642 km (223 471 mi).

Moon in descending node

Moon is in descending node in ♋ Cancer at 14:06 crossing the ecliptic from North to South to meet ascending node 13 days later on 1 September 2009 at 03:18 in ♑ Capricorn.

Previous nodeNext node

Draconic month

13 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the middle to the last part of the cycle.

Moon after northern standstill

2 days since the previous standstill on 15 August 2009 at 21:54 in ♊ Gemini when the Moon has reached North declination of ∠26.442°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-26.391° at the point of next southern standstill on 28 August 2009 at 20:17 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 1 day

In 1 day on 20 August 2009 at 10:01 in ♌ Leo 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.
