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 ♈ Aries

Moon is passing about ∠22° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1824"

Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1824" and ∠1951".

Wolf Moon after 7 days

Next Full Moon is the Wolf Moon of January 2031 after 7 days on 8 January 2031 at 18:26.

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.

Lunation 383 / 1336

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 383 of Meeus index or 1336 from Brown series.

Synodic month length 29.46 days

Length of current 383 lunation is 29 days, 10 hours and 59 minutes. It is 19 minutes shorter than next lunation 384 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 45 minutes shorter than the mean length of synodic month, but it is still 4 hours and 24 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠5.3°

This New Moon true anomaly is ∠5.3°. At beginning of next synodic month true anomaly will be ∠21.6°. 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 before apogee

8 days after point of perigee on 24 December 2030 at 10:09 in ♐ Sagittarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 4 days, until it get to the point of next apogee on 6 January 2031 at 11:00 in ♊ Gemini.

Distance to Moon 393 037 km

Moon is 393 037 km (244 222 mi) away from Earth on this date. Moon moves farther next 4 days until apogee, when Earth-Moon distance will reach 406 169 km (252 382 mi).

Moon before descending node

9 days after its ascending node on 23 December 2030 at 00:54 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 5 January 2031 at 06:37 in ♊ Gemini.

Draconic month

9 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

8 days after previous South standstill on 23 December 2030 at 18:07 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.904°. Next 4 days the lunar orbit moves northward to face North declination of ∠21.889° in the next northern standstill on 6 January 2031 at 05:22 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 8 January 2031 at 18:26 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
