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 ♐ Sagittarius
Moon is passing about ∠8° of ♐ Sagittarius tropical zodiac sector.
Apparent angular diameter ∠1922"
Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1900".
Harvest Moon after 7 days
Next Full Moon is the Harvest Moon of September 2055 after 7 days on 6 September 2055 at 01:56.
Upcoming main Moon phases
- Full Moon in Pisces ♓ on 6 September 2055 at 01:56
- Last Quarter in Gemini ♊ on 14 September 2055 at 05:14
- New Moon in Virgo ♍ on 21 September 2055 at 02:19

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 688 / 1641
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 688 of Meeus index or 1641 from Brown series.
Synodic month length 29.34 days
Length of current 688 lunation is 29 days, 8 hours and 5 minutes. This is the year's shortest synodic month of 2055. It is 25 minutes shorter than next lunation 689 length.
Lunation length shorter than mean
Length of current synodic month is 4 hours and 39 minutes shorter than the mean length of synodic month, but it is still 1 hour and 30 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠336.4°
This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly will be ∠352.8°. 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
5 days after point of perigee on 24 August 2055 at 04:11 in ♍ Virgo. 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 8 September 2055 at 13:59 in ♈ Aries.
Distance to Moon 372 979 km
Moon is 372 979 km (231 758 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 406 177 km (252 387 mi).
Moon before descending node
8 days after its ascending node on 21 August 2055 at 10:18 in ♌ Leo, the Moon is following the northern part of its orbit for the next 4 days, until it will cross the ecliptic from North to South in descending node on 3 September 2055 at 07:35 in ♒ Aquarius.
Draconic month
8 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
Moon before southern standstill
10 days after previous North standstill on 19 August 2055 at 08:07 in ♋ Cancer, when Moon has reached northern declination of ∠20.416°. Next 2 days the lunar orbit moves southward to face South declination of ∠-20.442° in the next southern standstill on 31 August 2055 at 23:31 in ♑ Capricorn.
Syzygy in 7 days
After 7 days on 6 September 2055 at 01:56 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
