Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 12 December 2019 at 05:12.

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 ∠7° of ♋ Cancer tropical zodiac sector.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2020 after 28 days on 10 January 2020 at 19:21.

Upcoming main Moon phases

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.

Lunation 246 / 1199

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 246 of Meeus index or 1199 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

Length of current 246 lunation is 29 days, 14 hours and 8 minutes. It is 2 hours and 21 minutes shorter than next lunation 247 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 23 minutes longer than the mean length of synodic month, but it is still 5 hours and 39 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠50.7°

This New Moon true anomaly is ∠50.7°. At beginning of next synodic month true anomaly will be ∠82.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before perigee

8 days after point of apogee on 5 December 2019 at 04:09 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 18 December 2019 at 20:30 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 378 964 km

Moon is 378 964 km (235 477 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 370 260 km (230 069 mi).

Moon in ascending node

Moon is in ascending node in ♋ Cancer at 14:15 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 26 December 2019 at 13:01 in ♑ Capricorn.

Previous nodeNext node

New draconic month

At 14:15 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon in northern standstill

At 20:57 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠23.226°. This is the year's northernmost lunar standstill of 2019. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-23.227° in its southern standstill point on 26 December 2019 at 20:11 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 12 days

After 12 days on 26 December 2019 at 05:13 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
