Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 99% and getting smaller. Lunar cycle is 15 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 ∠22° of ♊ Gemini tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 30 November 2020 at 09:30.

Beaver Moon before 1 day

Next Full Moon is the Cold Moon of December 2020 after 28 days on 30 December 2020 at 03:28.

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 ∠1801"

Lunar disc appears visually 7.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1946".

Lunation 258 / 1211

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 258 of Meeus index or 1211 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 9 minutes and it is 1 hour and 35 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 shorter than mean

The length of the current synodic month is 1 hour and 35 minutes shorter than the mean synodic month length. It is 4 hours and 34 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠12.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠12.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠30.1°.

Moon after apogee

4 days since point of apogee on 27 November 2020 at 00:29 in ♉ Taurus 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 12 December 2020 at 20:42 in ♏ Scorpio.

Distance to Moon 398 079 km

The Moon is 398 079 km (247 355 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 361 777 km (224 798 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 07:46 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 14 December 2020 at 11:03 in ♐ Sagittarius.

Moon before northern standstill

13 days since the last southern standstill on 18 November 2020 at 11:27 in ♑ Capricorn when the Moon has reached South declination of ∠-24.856° the lunar orbit is extending northward over the next day to face maximum declination of ∠24.882° at the point of next northern standstill on 3 December 2020 at 01:22 in ♋ Cancer.

New draconic month

At 07:46 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 13 days

In 13 days on 14 December 2020 at 16:17 in ♐ Sagittarius 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.
