Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 7 August 2055 at 10:57.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♈ Aries

Moon is passing about ∠16° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1769"

Lunar disc appears visually 6.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1894".

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September 2055 after 24 days on 6 September 2055 at 01:56.

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 687 / 1640

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 687 of Meeus index or 1640 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.35 days

Length of current 687 lunation is 29 days, 8 hours and 27 minutes. It is 22 minutes longer than next lunation 688 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 17 minutes shorter than the mean length of synodic month, but it is still 1 hour and 52 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠315.9°

This lunation true anomaly is ∠315.9°. At the beginning of next synodic month true anomaly will be ∠336.4°. 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 in apogee

Moon is reaching point of apogee on this date at 01:01, this is 15 days after last perigee on 27 July 2055 at 04:56 in ♍ Virgo. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 11 days ahead, until it will get to the point of next perigee on 24 August 2055 at 04:11 in ♍ Virgo.

Previous perigeeNext perigee

Distance to Moon 405 309 km

This apogee Moon is 405 309 km (251 847 mi) away from Earth. It is 99 km farther than the mean apogee distance, but it is still 1 400 km closer than the farthest apogee of 21st century.

Moon after descending node

5 days after its descending node on 7 August 2055 at 01:42 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 21 August 2055 at 10:18 in ♌ Leo.

Draconic month

18 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the second to the final part of it.

Moon before northern standstill

7 days after previous South standstill on 4 August 2055 at 18:05 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.399°. Next 6 days the lunar orbit moves northward to face North declination of ∠20.416° in the next northern standstill on 19 August 2055 at 08:07 in ♋ Cancer.

Syzygy in 10 days

After 10 days on 22 August 2055 at 18:14 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
