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 leaving the last ∠1° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Apparent angular diameter ∠1961"
Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1961" and ∠1950".
Wolf Moon after 7 days
Next Full Moon is the Wolf Moon of January 2051 after 7 days on 26 January 2051 at 21:20.
Upcoming main Moon phases
- Full Moon in Leo ♌ on 26 January 2051 at 21:20
- Last Quarter in Scorpio ♏ on 4 February 2051 at 01:40
- New Moon in Aquarius ♒ on 11 February 2051 at 06:41
- First Quarter in Taurus ♉ on 17 February 2051 at 22:16
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 631 / 1584
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 631 of Meeus index or 1584 from Brown series.
Synodic month length 29.49 days
Length of current 631 lunation is 29 days, 11 hours and 43 minutes. It is 1 hour and 32 minutes longer than next lunation 632 length.
Lunation length shorter than mean
Length of current synodic month is 1 hour and 1 minute shorter than the mean length of synodic month, but it is still 5 hours and 8 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠313.4°
This lunation true anomaly is ∠313.4°. At the beginning of next synodic month true anomaly will be ∠334.7°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
Moon after perigee
3 days after point of perigee on 15 January 2051 at 18:23 in ♒ Aquarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 31 January 2051 at 19:46 in ♎ Libra.
Distance to Moon 365 530 km
Moon is 365 530 km (227 130 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 405 173 km (251 763 mi).
Moon before descending node
12 days after its ascending node on 7 January 2051 at 05:43 in ♏ Scorpio, 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 20 January 2051 at 03:36 in ♉ Taurus.
Draconic month
12 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
Moon before northern standstill
8 days after previous South standstill on 10 January 2051 at 12:25 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.761°. Next 3 days the lunar orbit moves northward to face North declination of ∠19.697° in the next northern standstill on 23 January 2051 at 08:46 in ♊ Gemini.
Syzygy in 7 days
After 7 days on 26 January 2051 at 21:20 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
