Waning Gibbous in Cancer

Waning Gibbous on . The illuminated surface of the moon is 84% and getting smaller. The lunar cycle is 18 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.

Moon phase and lunation details

Moon is entering ♋ Cancer

Moon is passing first ∠0° of ♋ Cancer tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 30 November 2020 at 09:30.

Beaver Moon before 4 days

Next Full Moon is the Cold Moon of December 2020 after 25 days on 30 December 2020 at 03:28.

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 ∠1860"

Lunar disc appears visually 4.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1860" and ∠1947".

Lunation 258 / 1211

The Moon is 18 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

7 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 8 days until the Moon reaches the point of next perigee on 12 December 2020 at 20:42 in ♏ Scorpio.

Distance to Moon 385 323 km

The Moon is 385 323 km (239 429 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 361 777 km (224 798 mi).

Moon after ascending node

3 days after ascending node on 1 December 2020 at 07:46 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 14 December 2020 at 11:03 in ♐ Sagittarius.

Moon after northern standstill

1 day since the last northern standstill on 3 December 2020 at 01:22 in ♋ Cancer when the Moon has reached North declination of ∠24.882° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-24.879° at the point of next southern standstill on 15 December 2020 at 22:23 in ♑ Capricorn.

Draconic month

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

Syzygy in 10 days

In 10 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.
