Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 6 January 2021 at 09:37.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon is entering ♐ Sagittarius

Moon is passing first ∠0° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1966"

Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1966" and ∠1951".

Wolf Moon after 19 days

Next Full Moon is the Wolf Moon of January 2021 after 19 days on 28 January 2021 at 19:16.

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 259 / 1212

The Moon is 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 259 of Meeus index or 1212 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.53 days

Length of current 259 lunation is 29 days, 12 hours and 44 minutes. It is 1 hour and 21 minutes shorter than next lunation 260 length.

Lunation length same as the mean

Length of current synodic month is equal to the mean length of synodic month. It is 6 hours and 9 minutes longer than the 21st century shortest and 7 hours and 3 minutes shorter than the 21st century longest synodic month.

Lunar orbit position on

True anomaly ∠30.1°

This New Moon true anomaly is ∠30.1°. At beginning of next synodic month true anomaly will be ∠53.8°. 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 15:39, this is 15 days after last apogee on 24 December 2020 at 16:32 in ♈ Aries. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the point of next apogee on 21 January 2021 at 13:11 in ♉ Taurus.

Previous apogeeNext apogee

Distance to Moon 367 390 km

This perigee Moon is 367 390 km (228 286 mi) away from Earth. It is 4 882 km closer than the mean perigee distance, but it is still 2 966 km farther than the closest perigee of 21st century.

Moon before descending node

11 days after its ascending node on 28 December 2020 at 15:03 in ♊ Gemini, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 10 January 2021 at 20:15 in ♐ Sagittarius.

Draconic month

11 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the beginning to the first part of it.

Moon before southern standstill

10 days after previous North standstill on 30 December 2020 at 07:53 in ♋ Cancer, when Moon has reached northern declination of ∠24.868°. Next 2 days the lunar orbit moves southward to face South declination of ∠-24.870° in the next southern standstill on 12 January 2021 at 08:18 in ♑ Capricorn.

Syzygy in 3 days

After 3 days on 13 January 2021 at 05:00 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
