Waning Gibbous in Aquarius

Waning Gibbous on . Illuminated surface of the Moon is 85% 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 in ♒ Aquarius

Moon is passing about ∠23° of ♒ Aquarius tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 26 June 2010 at 11:30.

Strawberry Moon before 4 days

Next Full Moon is the Buck Moon of July 2010 after 25 days on 26 July 2010 at 01:37.

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 ∠1768"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1887".

Lunation 129 / 1082

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 129 of Meeus index or 1082 from Brown series.

Synodic month length 29.35 days

The length of this lunation is 29 days, 8 hours and 26 minutes and it is 58 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 4 hours and 18 minutes shorter than the mean synodic month length. It is 1 hour and 51 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠311.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠311.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠332.7°.

Moon before apogee

14 days since point of perigee on 15 June 2010 at 14:54 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 day until the Moon reaches the point of next apogee on 1 July 2010 at 10:12 in ♓ Pisces.

Distance to Moon 405 312 km

The Moon is 405 312 km (251 849 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 036 km (251 678 mi).

Moon after ascending node

3 days after ascending node on 27 June 2010 at 01:19 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 11 July 2010 at 07:30 in ♋ Cancer.

Moon after southern standstill

5 days since the last southern standstill on 25 June 2010 at 05:09 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.038° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠25.043° at the point of next northern standstill on 9 July 2010 at 16:50 in ♊ Gemini.

Draconic month

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

Syzygy in 11 days

In 11 days on 11 July 2010 at 19:40 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.
