Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 27 August 2009 at 11:42.

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 in ♑ Capricorn

Moon is passing about ∠22° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1901".

Harvest Moon after 4 days

Next Full Moon is the Harvest Moon of September 2009 after 4 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 119 / 1072

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 119 of Meeus index or 1072 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.36 days

The length of the lunation is 29 days, 8 hours and 43 minutes. It is 2 hours and 6 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 4 hours and 1 minute shorter than the mean synodic month length. It is 2 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠20.3°

At the beginning of the lunation cycle the true anomaly is ∠20.3°. At the beginning of next synodic month the true anomaly is going to be ∠39.3°.

Moon at apogee

Moon is at apogee at 11:04. It is 12 days after previous perigee on 19 August 2009 at 04:53 in ♌ Leo. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 15 days, until point of next perigee on 16 September 2009 at 07:55 in ♌ Leo.

Previous perigeeNext perigee

Distance to Moon 405 269 km

This apogee Moon is 405 269 km (251 822 mi) away from Earth. It is 139 km further than the mean apogee distance, but it is still 1 440 km closer than the farthest apogee of 21st century.

Moon before ascending node

12 days after descending node on 18 August 2009 at 14:06 in ♋ Cancer. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 1 September 2009 at 03:18 in ♑ Capricorn.

Draconic month

26 days since the beginning of current draconic month in ♑ Capricorn, the Moon is navigating from the second to the final part of the cycle.

Moon after southern standstill

2 days since the previous standstill on 28 August 2009 at 20:17 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.391°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠26.289° at the point of next northern standstill on 12 September 2009 at 04:36 in ♊ Gemini.

Syzygy in 4 days

In 4 days on 4 September 2009 at 16:03 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
