First Quarter in Aquarius

First Quarter on . Illuminated surface of the Moon is 51% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 8 November 2081 at 09:40 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 ∠18° of ♒ Aquarius tropical zodiac sector.

Beaver Moon after 8 days

Next Full Moon is the Beaver Moon of November 2081 after 8 days on 16 November 2081 at 13:19.

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 ∠1787"

Lunar disc appears visually 8.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1787" and ∠1937".

Lunation 1012 / 1965

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 1012 of Meeus index or 1965 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 32 minutes and it is 2 hours and 20 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 1 hour and 12 minutes shorter than the mean synodic month length. It is 4 hours and 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠29.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠29.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠52.5°.

Moon before apogee

9 days since point of perigee on 30 October 2081 at 07:55 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 2 days until the Moon reaches the point of next apogee on 11 November 2081 at 04:54 in ♓ Pisces.

Distance to Moon 401 107 km

The Moon is 401 107 km (249 236 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 868 km (251 573 mi).

Moon before ascending node

11 days after descending node on 28 October 2081 at 09:25 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 10 November 2081 at 15:13 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 4 November 2081 at 12:34 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.291° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.201° at the point of next northern standstill on 19 November 2081 at 01:19 in ♊ Gemini.

Draconic month

25 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 8 days

In 8 days on 16 November 2081 at 13:19 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.
