First Quarter in Aquarius

First Quarter on . Illuminated surface of the Moon is 52% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 27 October 2055 at 07:53 UTC.

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♒ Aquarius

Moon is passing about ∠6° of ♒ Aquarius tropical zodiac sector.

Beaver Moon after 8 days

Next Full Moon is the Beaver Moon of November 2055 after 8 days on 4 November 2055 at 12:12.

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.

Apparent angular diameter ∠1832"

Lunar disc appears visually 5.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1832" and ∠1931".

Lunation 690 / 1643

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 690 of Meeus index or 1643 from Brown series.

Synodic month length 29.41 days

The length of this lunation is 29 days, 9 hours and 45 minutes and it is 1 hour and 56 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 59 minutes shorter than the mean synodic month length. It is 3 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠7.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠7.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠24.3°.

Moon before apogee

7 days since point of perigee on 19 October 2055 at 23:43 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next apogee on 1 November 2055 at 20:44 in ♈ Aries.

Distance to Moon 391 200 km

The Moon is 391 200 km (243 080 mi) away from Earth and getting further over the next 5 days until the point apogee when Earth-Moon distance is going to be 406 106 km (252 343 mi).

Moon in descending node

Moon is in descending node in ♒ Aquarius at 11:35 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 11 November 2055 at 01:13 in ♌ Leo.

Moon after southern standstill

1 day since the last southern standstill on 25 October 2055 at 12:52 in ♑ Capricorn when the Moon has reached South declination of ∠-20.867° the lunar orbit is extending northward over the next 12 days to face maximum declination of ∠21.007° at the point of next northern standstill on 9 November 2055 at 06:27 in ♋ Cancer.

Draconic month

12 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the middle to the last part of the lunar cycle.

Syzygy in 8 days

In 8 days on 4 November 2055 at 12:12 in ♉ Taurus the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
