Moon phase and lunation details

Moonrise and moonset

Moon in ♊ Gemini

Moon is passing about ∠12° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1823"

Lunar disc appears visually 4.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1823" and ∠1907".

Next Full Moon is the Hunter Moon of October 2055 after 22 days on 5 October 2055 at 18:38.

Upcoming main Moon phases

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 21 days old. Earth's natural satellite is moving through the last 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 apogee

4 days after point of apogee on 8 September 2055 at 13:59 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 21 September 2055 at 12:32 in ♎ Libra.

Distance to Moon 393 168 km

Moon is 393 168 km (244 303 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 357 315 km (222 025 mi).

Moon before ascending node

10 days after its descending node on 3 September 2055 at 07:35 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 17 September 2055 at 19:18 in ♌ Leo.

Moon before northern standstill

12 days after previous South standstill on 31 August 2055 at 23:31 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.442°. Next 2 days the lunar orbit moves northward to face North declination of ∠20.530° in the next northern standstill on 15 September 2055 at 17:00 in ♋ Cancer.

Syzygy in 7 days

After 7 days on 21 September 2055 at 02:19 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
