Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♍ Virgo

Moon is passing about ∠17° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1950".

Wolf Moon after 23 days

Next Full Moon is the Wolf Moon of January 2020 after 23 days on 10 January 2020 at 19:21.

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 246 / 1199

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 246 of Meeus index or 1199 from Brown series.

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 in perigee

Moon is reaching point of perigee on this date at 20:30, this is 13 days after last apogee on 5 December 2019 at 04:09 in ♓ Pisces. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 14 days ahead, until it will get to the point of next apogee on 2 January 2020 at 01:30 in ♓ Pisces.

Distance to Moon 370 260 km

This perigee Moon is 370 260 km (230 069 mi) away from Earth. This is the year's farthest perigee of 2019. It is 7 752 km closer than the mean perigee distance, but it is still 96 km farther than the closest perigee of 21st century.

Moon after ascending node

4 days after its ascending node on 13 December 2019 at 14:15 in ♋ Cancer, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 26 December 2019 at 13:01 in ♑ Capricorn.

Moon after northern standstill

4 days after previous North standstill on 13 December 2019 at 20:57 in ♋ Cancer, when Moon has reached northern declination of ∠23.226°. Next 8 days the lunar orbit moves southward to face South declination of ∠-23.227° in the next southern standstill on 26 December 2019 at 20:11 in ♑ Capricorn.

Syzygy in 7 days

After 7 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.
