Waxing Gibbous in Sagittarius

Waxing Gibbous on . Illuminated surface of the Moon is 75% and growing larger. Lunar cycle is 10 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 in ♐ Sagittarius

Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 28 July 2009 at 22:00.

Sturgeon Moon after 5 days

Next Full Moon is the Sturgeon Moon of August 2009 after 5 days on 6 August 2009 at 00:55.

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 ∠1797"

Lunar disc appears visually 5.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1797" and ∠1890".

Lunation 118 / 1071

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 118 of Meeus index or 1071 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 27 minutes and it is 1 hour and 16 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 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 details for

True anomaly ∠4.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠4.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠20.3°.

Moon before apogee

9 days since point of perigee on 21 July 2009 at 20:16 in ♋ Cancer the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 4 August 2009 at 00:42 in ♑ Capricorn.

Distance to Moon 398 897 km

The Moon is 398 897 km (247 863 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 406 027 km (252 293 mi).

Moon before ascending node

9 days after descending node on 22 July 2009 at 03:47 in ♌ Leo the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 4 August 2009 at 21:42 in ♑ Capricorn.

Moon before southern standstill

11 days since the last northern standstill on 19 July 2009 at 13:01 in ♊ Gemini when the Moon has reached North declination of ∠26.477° the lunar orbit is extending southward over the next day to face maximum declination of ∠-26.478° at the point of next southern standstill on 1 August 2009 at 13:28 in ♐ Sagittarius.

Draconic month

22 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 5 days

In 5 days on 6 August 2009 at 00:55 in ♒ Aquarius 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.
