First Quarter in Aquarius

First Quarter on . Illuminated surface of the Moon is 60% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 13 October 2097 at 09:35 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 is entering ♒ Aquarius

Moon is passing first ∠4° of ♒ Aquarius tropical zodiac sector.

Hunter Moon after 6 days

Next Full Moon is the Hunter Moon of October 2097 after 6 days on 21 October 2097 at 01:23.

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 ∠1775"

Lunar disc appears visually 8.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1925".

Lunation 1209 / 2162

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 1209 of Meeus index or 2162 from Brown series.

Synodic month length 29.6 days

The length of this lunation is 29 days, 14 hours and 23 minutes and it is 2 hours 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 1 hour and 39 minutes longer than the mean synodic month length. It is 5 hours and 24 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠76.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠76.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠112.4°.

Moon after apogee

1 day since point of apogee on 12 October 2097 at 16:09 in ♑ Capricorn the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 24 October 2097 at 15:32 in ♊ Gemini.

Distance to Moon 403 760 km

The Moon is 403 760 km (250 885 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 367 167 km (228 147 mi).

Moon before ascending node

7 days after descending node on 7 October 2097 at 00:55 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 October 2097 at 09:50 in ♉ Taurus.

Moon after southern standstill

2 days since the last southern standstill on 12 October 2097 at 03:02 in ♑ Capricorn when the Moon has reached South declination of ∠-27.965° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠27.974° at the point of next northern standstill on 25 October 2097 at 18:37 in ♊ Gemini.

Draconic month

20 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 21 October 2097 at 01:23 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.
