Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 90% and getting smaller. Lunar cycle is 17 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 in ♒ Aquarius

Moon is passing about ∠15° of ♒ Aquarius tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 28 June 2018 at 04:53.

Strawberry Moon before 3 days

Next Full Moon is the Buck Moon of July 2018 after 26 days on 27 July 2018 at 20:20.

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 ∠1773"

Lunar disc appears visually 6.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1773" and ∠1887".

Lunation 228 / 1181

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 228 of Meeus index or 1181 from Brown series.

Synodic month length 29.3 days

The length of this lunation is 29 days, 7 hours and 5 minutes and it is 5 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2018. 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 39 minutes shorter than the mean synodic month length. It is 30 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠340.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠340.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠356°.

Moon after apogee

1 day since point of apogee on 30 June 2018 at 02:43 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 13 July 2018 at 08:28 in ♋ Cancer.

Distance to Moon 404 261 km

The Moon is 404 261 km (251 196 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 357 432 km (222 098 mi).

Moon after descending node

1 day after descending node on 30 June 2018 at 16:44 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 14 July 2018 at 02:50 in ♌ Leo.

Moon after southern standstill

2 days since the last southern standstill on 28 June 2018 at 14:30 in ♑ Capricorn when the Moon has reached South declination of ∠-20.775° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠20.761° at the point of next northern standstill on 12 July 2018 at 12:01 in ♋ Cancer.

Draconic month

14 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 13 July 2018 at 02:48 in ♋ Cancer 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.
