Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 15 August 2055 at 14:26.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♊ Gemini

Moon is passing about ∠17° of ♊ Gemini tropical zodiac sector.

Next Full Moon is the Harvest Moon of September 2055 after 19 days on 6 September 2055 at 01:56.

Upcoming main Moon phases

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 24 days old. Earth's natural satellite is moving from the second to the final 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 after apogee

5 days after point of apogee on 12 August 2055 at 01:01 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 6 days, until it get to the point of next perigee on 24 August 2055 at 04:11 in ♍ Virgo.

Distance to Moon 390 482 km

Moon is 390 482 km (242 634 mi) away from Earth on this date. Moon moves closer next 6 days until perigee, when Earth-Moon distance will reach 360 218 km (223 829 mi).

Moon before ascending node

10 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 3 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

23 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

12 days after previous South standstill on 4 August 2055 at 18:05 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.399°. Next day 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 5 days

After 5 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.
