Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 61% and getting smaller. The lunar cycle is 21 days old.

Moonrise and moonset

The 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 ♊ Gemini

Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 30 August 2004 at 02:22.

Sturgeon Moon before 6 days

Next Full Moon is the Harvest Moon of September 2004 after 23 days on 28 September 2004 at 13:09.

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 ∠1784"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1784" and ∠1904".

Lunation 57 / 1010

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 57 of Meeus index or 1010 from Brown series.

Synodic month length 29.55 days

The length of this lunation is 29 days, 13 hours and 5 minutes and it is 46 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 longer than mean

The length of the current synodic month is 21 minutes longer than the mean synodic month length. It is 6 hours and 42 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠234°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠234° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠269.4°.

Moon before apogee

9 days since point of perigee on 27 August 2004 at 05:37 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 8 September 2004 at 02:42 in ♋ Cancer.

Distance to Moon 401 815 km

The Moon is 401 815 km (249 676 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 464 km (251 322 mi).

Moon after ascending node

2 days after ascending node on 3 September 2004 at 06:34 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 17 September 2004 at 14:51 in ♎ Libra.

Moon before northern standstill

10 days since the last southern standstill on 25 August 2004 at 20:48 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.776° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠27.870° at the point of next northern standstill on 8 September 2004 at 09:40 in ♋ Cancer.

Draconic month

2 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 14 September 2004 at 14:29 in ♍ Virgo 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.
