Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 71% and getting smaller. Lunar cycle is 20 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 ♊ Gemini

Moon is passing about ∠9° of ♊ Gemini tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 21 September 2002 at 13:59.

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2002 after 23 days on 21 October 2002 at 07:20.

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 ∠1810"

Lunar disc appears visually 5.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1810" and ∠1915".

Lunation 33 / 986

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 33 of Meeus index or 986 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 7 minutes and it is 1 hour and 10 minutes shorter 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 37 minutes shorter than the mean synodic month length. It is 1 hour and 32 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠343.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠343.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠358.6°.

Moon after apogee

4 days since point of apogee on 23 September 2002 at 03:26 in ♈ Aries the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 6 October 2002 at 13:17 in ♎ Libra.

Distance to Moon 396 072 km

The Moon is 396 072 km (246 108 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 356 920 km (221 780 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 16:06 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 10 October 2002 at 07:07 in ♐ Sagittarius.

Moon before northern standstill

12 days since the last southern standstill on 15 September 2002 at 05:34 in ♑ Capricorn when the Moon has reached South declination of ∠-25.377° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.530° at the point of next northern standstill on 30 September 2002 at 00:04 in ♋ Cancer.

New draconic month

At 16:06 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 8 days

In 8 days on 6 October 2002 at 11:17 in ♎ Libra 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.
