Waning Gibbous in Cancer

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 8 December 2098 at 13:45.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2099 after 28 days on 7 January 2099 at 01:50.

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 ∠1923"

Lunar disc appears visually 1.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1923" and ∠1948".

Lunation 1223 / 2176

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1223 of Meeus index or 2176 from Brown series.

Synodic month length 29.65 days

The length of this lunation is 29 days, 15 hours and 33 minutes and it is 2 hours and 10 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 49 minutes longer than the mean synodic month length. It is 4 hours and 14 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠78.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠78.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠115.9°.

Moon before perigee

9 days since point of apogee on 30 November 2098 at 00:33 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 11 December 2098 at 21:02 in ♋ Cancer.

Distance to Moon 372 701 km

The Moon is 372 701 km (231 586 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 366 722 km (227 870 mi).

Moon after ascending node

5 days after ascending node on 3 December 2098 at 17:44 in ♈ Aries the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 16 December 2098 at 15:17 in ♎ Libra.

Moon at northern standstill

At 15:23 the Moon is meeting its standstill point to reach North declination of ∠28.352°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.323° at the point of next southern standstill in ♐ Sagittarius on 22 December 2098 at 16:33.

Draconic month

5 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 13 days

In 13 days on 22 December 2098 at 15:24 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.
