Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 3 December 2017 at 15:47.

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.

Moon in ♋ Cancer

Moon is passing about ∠10° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1947".

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2018 after 27 days on 2 January 2018 at 02:24.

Upcoming main Moon phases

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.

Lunation 221 / 1174

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 221 of Meeus index or 1174 from Brown series.

Synodic month length 29.78 days

The length of the lunation is 29 days, 18 hours and 48 minutes. It is 59 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 6 hours and 4 minutes longer than the mean synodic month length. It is 59 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠147°

At the beginning of the lunation cycle the true anomaly is ∠147°. At the beginning of next synodic month the true anomaly is going to be ∠173.3°.

Moon after perigee

1 day after point of perigee on 4 December 2017 at 08:42 in ♊ Gemini. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 13 days, until the Moon reaches the point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.

Previous perigeeNext apogee

Distance to Moon 363 411 km

The Moon is 363 411 km (225 813 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 605 km (252 653 mi).

Moon before ascending node

10 days after descending node on 25 November 2017 at 08:22 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 2 days, until the lunar orbit crosses from South to North in ascending node on 8 December 2017 at 00:39 in ♌ Leo.

Draconic month

24 days since the beginning of current draconic month in ♌ Leo, the Moon is navigating from the second to the final part of the cycle.

Moon at northern standstill

At 11:43 the Moon is meeting its standstill point to reach North declination of ∠20.015°. This is the year's northernmost lunar standstill of 2017. Over the next 13 days the lunar orbit is going to extend southward to face maximum declination of ∠-20.062° at the point of next standstill in ♑ Capricorn on 19 December 2017 at 09:31.

Syzygy in 12 days

In 12 days on 18 December 2017 at 06:31 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.
