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 19 October 2007 at 08:33 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 ∠10° of ♒ Aquarius tropical zodiac sector.

Hunter Moon after 5 days

Next Full Moon is the Hunter Moon of October 2007 after 5 days on 26 October 2007 at 04:52.

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 ∠1871"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1871" and ∠1927".

Lunation 96 / 1049

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 96 of Meeus index or 1049 from Brown series.

Synodic month length 29.75 days

The length of this lunation is 29 days, 18 hours and 2 minutes and it is 35 minutes shorter than the upcoming lunation's length. 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 longer than mean

The length of the current synodic month is 5 hours and 18 minutes longer than the mean synodic month length. It is 1 hour and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠159.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠159.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠183.8°.

Moon before perigee

7 days since point of apogee on 13 October 2007 at 09:53 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 26 October 2007 at 11:51 in ♉ Taurus.

Distance to Moon 383 107 km

The Moon is 383 107 km (238 052 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 356 755 km (221 677 mi).

Moon before ascending node

12 days after descending node on 7 October 2007 at 20:03 in ♍ Virgo the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 22 October 2007 at 09:02 in ♓ Pisces.

Moon after southern standstill

3 days since the last southern standstill on 16 October 2007 at 23:14 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.194° the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠28.117° at the point of next northern standstill on 29 October 2007 at 18:09 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 5 days

In 5 days on 26 October 2007 at 04:52 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.
