Waxing Gibbous in Aquarius

Waxing Gibbous on . Illuminated surface of the Moon is 91% and growing larger. Lunar cycle is 12 days young.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠4° of ♒ Aquarius tropical zodiac sector.

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 27 August 2009 at 11:42.

Harvest Moon after 3 days

Next Full Moon is the Harvest Moon of September 2009 after 3 days on 4 September 2009 at 16:03.

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.

Apparent angular diameter ∠1769"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1902".

Lunation 119 / 1072

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 119 of Meeus index or 1072 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 43 minutes and it is 2 hours and 6 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 details for

True anomaly ∠20.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠20.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠39.3°.

Moon after apogee

1 day since point of apogee on 31 August 2009 at 11:04 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 14 days until the Moon reaches the point of next perigee on 16 September 2009 at 07:55 in ♌ Leo.

Distance to Moon 405 266 km

The Moon is 405 266 km (251 821 mi) away from Earth and getting closer over the next 14 days until the point perigee when Earth-Moon distance is going to be 364 054 km (226 213 mi).

Moon in ascending node

Moon is in ascending node in ♑ Capricorn at 03:18 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 14 September 2009 at 20:56 in ♋ Cancer.

Moon after southern standstill

3 days since the last southern 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 10 days to face maximum declination of ∠26.289° at the point of next northern standstill on 12 September 2009 at 04:36 in ♊ Gemini.

New draconic month

At 03:18 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 3 days

In 3 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.
