First Quarter in Aquarius

First Quarter on . The illuminated surface of the moon is 61% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 24 October 2039 at 11:50 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 in ♒ Aquarius

Moon is passing about ∠15° of ♒ Aquarius tropical zodiac sector.

Hunter Moon after 6 days

Next Full Moon is the Hunter Moon of October 2039 after 6 days on 31 October 2039 at 22:36.

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 ∠1934"

Lunar disc appears visually 0.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1934" and ∠1930".

Lunation 492 / 1445

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 492 of Meeus index or 1445 from Brown series.

Synodic month length 29.44 days

The length of this lunation is 29 days, 10 hours and 37 minutes and it is 9 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2039. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 2 hours and 7 minutes shorter than the mean synodic month length. It is 4 hours and 2 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠321.1°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠321.1° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠340.7°.

Moon after perigee

5 days since point of perigee on 20 October 2039 at 05:11 in ♏ Scorpio the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 5 November 2039 at 04:29 in ♊ Gemini.

Distance to Moon 370 678 km

The Moon is 370 678 km (230 329 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 405 534 km (251 987 mi).

Moon after descending node

4 days after descending node on 21 October 2039 at 04:37 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 3 November 2039 at 19:55 in ♊ Gemini.

Moon after southern standstill

2 days since the last southern standstill on 23 October 2039 at 01:02 in ♑ Capricorn when the Moon has reached South declination of ∠-25.344° the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠25.428° at the point of next northern standstill on 6 November 2039 at 03:44 in ♋ Cancer.

Draconic month

17 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 6 days

In 6 days on 31 October 2039 at 22:36 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.
