Waning Gibbous in Gemini

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 is entering ♊ Gemini

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

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 14 October 2008 at 20:03.

Hunter Moon before 2 days

Next Full Moon is the Beaver Moon of November 2008 after 26 days on 13 November 2008 at 06:17.

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 ∠1967"

Lunar disc appears visually 2.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1926".

Lunation 108 / 1061

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 108 of Meeus index or 1061 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 2 minutes and it is 2 hours and 39 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 longer than mean

The length of the current synodic month is 2 hours and 18 minutes longer than the mean synodic month length. It is 4 hours and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠98.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠98.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠133.4°.

Moon at perigee

Moon is at perigee at 06:06 about 11 days since last apogee on 5 October 2008 at 10:34 in ♐ Sagittarius the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 2 November 2008 at 04:55 in ♐ Sagittarius.

Distance to Moon 363 828 km

This perigee Moon is 363 828 km (226 072 mi) away from Earth. It is 1 320 km closer than the mean perigee distance, but it is still 6 528 km further than the closest perigee of 21st century.

Moon before descending node

7 days after ascending node on 10 October 2008 at 00:38 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 22 October 2008 at 18:00 in ♌ Leo.

Moon before northern standstill

11 days since the last southern standstill on 5 October 2008 at 14:05 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.370° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.270° at the point of next northern standstill on 19 October 2008 at 00:21 in ♋ Cancer.

Draconic month

7 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 11 days

In 11 days on 28 October 2008 at 23:14 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.
