Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♉ Taurus

Moon is passing about ∠12° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1799"

Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1799" and ∠1948".

Snow Moon after 8 days

Next Full Moon is the Snow Moon of February 2031 after 8 days on 7 February 2031 at 12:46.

Upcoming main Moon phases

Moderate tide

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.

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 384 of Meeus index or 1337 from Brown series.

Synodic month length 29.47 days

Length of current 384 lunation is 29 days, 11 hours and 18 minutes. It is 42 minutes shorter than next lunation 385 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 26 minutes shorter than the mean length of synodic month, but it is still 4 hours and 43 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠21.6°

This New Moon true anomaly is ∠21.6°. At beginning of next synodic month true anomaly will be ∠41.9°. 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 apogee

8 days after point of perigee on 21 January 2031 at 21:41 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.

Distance to Moon 398 508 km

Moon is 398 508 km (247 621 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 405 416 km (251 914 mi).

Moon before descending node

11 days after its ascending node on 19 January 2031 at 08:51 in ♐ Sagittarius, 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 1 February 2031 at 09:25 in ♊ Gemini.

Moon before northern standstill

10 days after previous South standstill on 20 January 2031 at 05:10 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.824°. Next 3 days the lunar orbit moves northward to face North declination of ∠21.745° in the next northern standstill on 2 February 2031 at 12:52 in ♊ Gemini.

Syzygy in 8 days

After 8 days on 7 February 2031 at 12:46 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
