First Quarter in Aquarius

First Quarter on . The illuminated surface of the moon is 62% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 11 October 2043 at 07:05 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon is entering ♒ Aquarius

Moon is passing first ∠3° of ♒ Aquarius tropical zodiac sector.

Hunter Moon after 5 days

Next Full Moon is the Hunter Moon of October 2043 after 5 days on 18 October 2043 at 11:56.

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 ∠1817"

Lunar disc appears visually 5.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1817" and ∠1923".

Lunation 541 / 1494

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 541 of Meeus index or 1494 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 45 minutes and it is 1 hour and 55 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 longer than mean

The length of the current synodic month is 4 hours and 1 minute longer than the mean synodic month length. It is 3 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠123.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠123.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠154°.

Moon after apogee

4 days since point of apogee on 7 October 2043 at 22:24 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 19 October 2043 at 23:27 in ♉ Taurus.

Distance to Moon 394 544 km

The Moon is 394 544 km (245 158 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 360 242 km (223 844 mi).

Moon before ascending node

10 days after descending node on 2 October 2043 at 07:39 in ♍ Virgo the Moon is positioned south of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from South to North in ascending node on 16 October 2043 at 17:59 in ♓ Pisces.

Moon after southern standstill

2 days since the last southern standstill on 9 October 2043 at 19:46 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.686° the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠28.637° at the point of next northern standstill on 22 October 2043 at 21:04 in ♊ Gemini.

Draconic month

23 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 5 days

In 5 days on 18 October 2043 at 11:56 in ♈ Aries 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.
