Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 88% and getting smaller. Lunar cycle is 18 days old.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

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 ∠2° of ♒ Aquarius tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 7 June 2009 at 18:12.

Strawberry Moon before 3 days

Next Full Moon is the Buck Moon of July 2009 after 25 days on 7 July 2009 at 09:21.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1770"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1890".

Lunation 116 / 1069

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 116 of Meeus index or 1069 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 24 minutes and it is 24 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 5 hours and 20 minutes shorter than the mean synodic month length. It is 49 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠332.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠332.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠349.4°.

Moon after apogee

1 day since point of apogee on 10 June 2009 at 16:04 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 23 June 2009 at 10:39 in ♋ Cancer.

Distance to Moon 404 891 km

The Moon is 404 891 km (251 588 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 358 018 km (222 462 mi).

Moon in ascending node

Moon is in ascending node in ♒ Aquarius at 10:15 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 24 June 2009 at 17:24 in ♋ Cancer.

Moon after southern standstill

3 days since the last southern standstill on 8 June 2009 at 02:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.429° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠26.446° at the point of next northern standstill on 22 June 2009 at 02:48 in ♊ Gemini.

New draconic month

At 10:15 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 11 days

In 11 days on 22 June 2009 at 19:35 in ♊ Gemini 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.
