Moon phase and lunation details
Moonrise and moonset
Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.
Moon in ♒ Aquarius
Moon is passing about ∠8° of ♒ Aquarius tropical zodiac sector.
Apparent angular diameter
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1949" and ∠1949".
Snow Moon after 15 days
Next Full Moon is the Snow Moon of February 2031 after 15 days on 7 February 2031 at 12:46.
Upcoming main Moon phases
- First Quarter in Taurus ♉ on 30 January 2031 at 07:43
- Full Moon in Leo ♌ on 7 February 2031 at 12:46
- Last Quarter in Scorpio ♏ on 14 February 2031 at 22:50
- New Moon in Aquarius ♒ on 21 February 2031 at 15:49
Spring tide
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
New lunation 384 / 1337
At 04:31 on this date the Moon completes the old and enters a new synodic month with lunation 384 of Meeus index or 1337 from Brown series.
Synodic month length 29.47 days
29 days, 11 hours and 18 minutes is the length of new lunation 384. 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 after perigee
1 day 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 10 days, until it get to the point of next apogee on 2 February 2031 at 23:45 in ♊ Gemini.
Distance to Moon 367 800 km
Moon is 367 800 km (228 540 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 405 416 km (251 914 mi).
Moon after ascending node
4 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 8 days, until it will cross the ecliptic from North to South in descending node on 1 February 2031 at 09:25 in ♊ Gemini.
Draconic month
4 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.
Moon after southern standstill
3 days after previous South standstill on 20 January 2031 at 05:10 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.824°. Next 10 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.
Sun-Moon-Earth syzygy
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
