First Quarter in Aquarius

First Quarter on . Illuminated surface of the Moon is 45% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 17 November 2007 at 22:32 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 ∠19° of ♒ Aquarius tropical zodiac sector.

Beaver Moon after 7 days

Next Full Moon is the Beaver Moon of November 2007 after 7 days on 24 November 2007 at 14:30.

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 ∠1881"

Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1881" and ∠1941".

Lunation 97 / 1050

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 97 of Meeus index or 1050 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 37 minutes and it is 40 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2007. 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 53 minutes longer than the mean synodic month length. It is 1 hour and 10 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠183.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠183.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠209.6°.

Moon before perigee

7 days since point of apogee on 9 November 2007 at 12:31 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next perigee on 24 November 2007 at 00:12 in ♊ Gemini.

Distance to Moon 381 078 km

The Moon is 381 078 km (236 791 mi) away from Earth and getting closer over the next 6 days until the point perigee when Earth-Moon distance is going to be 357 196 km (221 951 mi).

Moon before ascending node

13 days after descending node on 3 November 2007 at 22:09 in ♌ Leo 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 18 November 2007 at 12:46 in ♓ Pisces.

Moon after southern standstill

4 days since the last southern standstill on 13 November 2007 at 04:37 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.006° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠27.958° at the point of next northern standstill on 26 November 2007 at 03:58 in ♊ Gemini.

Draconic month

26 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 7 days

In 7 days on 24 November 2007 at 14:30 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.
