Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 6 September 2055 at 01:56.

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 is entering ♈ Aries

Moon is passing first ∠0° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1769"

Lunar disc appears visually 7.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1904".

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2055 after 28 days on 5 October 2055 at 18:38.

Upcoming main Moon phases

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 688 / 1641

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 688 of Meeus index or 1641 from Brown series.

PreviousCurrent lunationNext

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 before apogee

14 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 day, until it get to the point of next apogee on 8 September 2055 at 13:59 in ♈ Aries.

Previous perigeeNext apogee

Distance to Moon 405 247 km

Moon is 405 247 km (251 809 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 406 177 km (252 387 mi).

Moon after descending node

4 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 10 days, until it will cross the ecliptic from South to North in ascending node on 17 September 2055 at 19:18 in ♌ Leo.

Draconic month

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

Moon after southern standstill

6 days after previous South standstill on 31 August 2055 at 23:31 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.442°. Next 8 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 13 days

After 13 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.
