Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 22 December 2018 at 17:49.

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 ♌ Leo

Moon is passing about ∠12° of ♌ Leo tropical zodiac sector.

Cold Moon before 2 days

Next Full Moon is the Wolf Moon of January 2019 after 26 days on 21 January 2019 at 05:16.

Upcoming main Moon phases

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 234 / 1187

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 234 of Meeus index or 1187 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.76 days

Length of current 234 lunation is 29 days, 18 hours and 8 minutes. It is 1 hour and 27 minutes shorter than next lunation 235 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 24 minutes longer than the mean length of synodic month, but it is still 1 hour and 39 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠116.6°

This New Moon true anomaly is ∠116.6°. At beginning of next synodic month true anomaly will be ∠149.4°. 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 after perigee

1 day after point of perigee on 24 December 2018 at 09:52 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 14 days, until it get to the point of next apogee on 9 January 2019 at 04:29 in ♒ Aquarius.

Distance to Moon 363 357 km

Moon is 363 357 km (225 780 mi) away from Earth on this date. Moon moves farther next 14 days until apogee, when Earth-Moon distance will reach 406 116 km (252 349 mi).

Moon after ascending node

1 day after its ascending node on 24 December 2018 at 11:54 in ♋ Cancer, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 7 January 2019 at 00:08 in ♒ Aquarius.

Moon after northern standstill

2 days after previous North standstill on 23 December 2018 at 11:48 in ♋ Cancer, when Moon has reached northern declination of ∠21.550°. Next 11 days the lunar orbit moves southward to face South declination of ∠-21.553° in the next southern standstill on 5 January 2019 at 18:45 in ♑ Capricorn.

Syzygy in 11 days

After 11 days on 6 January 2019 at 01:28 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
