Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day 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 ♋ Cancer

Moon is leaving the last ∠3° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1967"

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

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.

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 234 / 1187

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 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 in perigee

Moon is reaching point of perigee on this date at 09:52, this is 11 days after last apogee on 12 December 2018 at 12:25 in ♒ Aquarius. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 15 days ahead, until it will get to the point of next apogee on 9 January 2019 at 04:29 in ♒ Aquarius.

Previous apogeeNext apogee

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 farther than the closest perigee of 21st century.

Moon in ascending node

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

Previous nodeNext node

New draconic month

At 11:54 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon after northern standstill

1 day after previous North standstill on 23 December 2018 at 11:48 in ♋ Cancer, when Moon has reached northern declination of ∠21.550°. Next 12 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 12 days

After 12 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.
