Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 96% and getting smaller. Lunar cycle is 16 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 leaving the last ∠3° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 22 December 2018 at 17:49.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2019 after 27 days on 21 January 2019 at 05:16.

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 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1951".

Lunation 234 / 1187

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 234 of Meeus index or 1187 from Brown series.

Synodic month length 29.76 days

The length of this lunation is 29 days, 18 hours and 8 minutes and it is 1 hour and 27 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 5 hours and 24 minutes longer than the mean synodic month length. It is 1 hour and 39 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠116.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠116.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠149.4°.

Moon at perigee

Moon is at perigee at 09:52 about 11 days since last apogee on 12 December 2018 at 12:25 in ♒ Aquarius 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 9 January 2019 at 04:29 in ♒ Aquarius.

Distance to Moon 361 060 km

This perigee Moon is 361 060 km (224 352 mi) away from Earth. It is 1 448 km closer than the mean perigee distance, but it is still 9 296 km further than the closest perigee of 21st century.

Moon in ascending node

Moon is in ascending node in ♋ Cancer at 11:54 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 7 January 2019 at 00:08 in ♒ Aquarius.

Moon after northern standstill

1 day since the last northern standstill on 23 December 2018 at 11:48 in ♋ Cancer when the Moon has reached North declination of ∠21.550° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-21.553° at the point of next southern standstill on 5 January 2019 at 18:45 in ♑ Capricorn.

New draconic month

At 11:54 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 12 days

In 12 days on 6 January 2019 at 01:28 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.
