Waning Gibbous in Cancer

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 ♋ Cancer

Moon is passing about ∠13° of ♋ Cancer tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 22 December 2037 at 13:38.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2038 after 28 days on 21 January 2038 at 04:00.

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 ∠1878"

Lunar disc appears visually 3.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1878" and ∠1951".

Lunation 469 / 1422

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 469 of Meeus index or 1422 from Brown series.

Synodic month length 29.59 days

The length of this lunation is 29 days, 14 hours and 3 minutes and it is 2 hours and 8 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 1 hour and 19 minutes longer than the mean synodic month length. It is 5 hours and 44 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠48°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠48° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠79.2°.

Moon before perigee

7 days since point of apogee on 15 December 2037 at 16:34 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 29 December 2037 at 18:48 in ♎ Libra.

Distance to Moon 381 575 km

The Moon is 381 575 km (237 100 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 370 285 km (230 084 mi).

Moon in ascending node

Moon is in ascending node in ♋ Cancer at 22:59 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 5 January 2038 at 21:32 in ♑ Capricorn.

Moon at northern standstill

At 09:44 the Moon is meeting its standstill point to reach North declination of ∠22.193°. This is the year's northernmost lunar standstill of 2037. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-22.189° at the point of next southern standstill in ♑ Capricorn on 5 January 2038 at 08:13.

New draconic month

At 22:59 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 5 January 2038 at 13:41 in ♑ Capricorn 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.
