First Quarter in Pisces

First Quarter on . Illuminated surface of the Moon is 58% and growing larger. Lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 13 November 2010 at 16:39 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 ♓ Pisces

Moon is passing first ∠1° of ♓ Pisces tropical zodiac sector.

Beaver Moon after 7 days

Next Full Moon is the Beaver Moon of November 2010 after 7 days on 21 November 2010 at 17:27.

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 ∠1771"

Lunar disc appears visually 9.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1940".

Lunation 134 / 1087

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 134 of Meeus index or 1087 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 44 minutes and it is 2 hours and 43 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 same as the mean

The length of the current synodic month is equal to the mean synodic month length. It is %hours_to_shortest% and %minutes_to_shortest% longer than the 21st century's shortest and %hours_to_longest% and %minutes_to_longest% shorter than the 21st century's longest synodic months.

Lunar orbit details for

True anomaly ∠39.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠39.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠67°.

Moon before apogee

10 days since point of perigee on 3 November 2010 at 17:22 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 15 November 2010 at 11:47 in ♓ Pisces.

Distance to Moon 404 783 km

The Moon is 404 783 km (251 520 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 634 km (251 428 mi).

Moon after ascending node

4 days after ascending node on 9 November 2010 at 20:14 in ♐ Sagittarius the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 24 November 2010 at 06:27 in ♋ Cancer.

Moon after southern standstill

5 days since the last southern standstill on 8 November 2010 at 16:59 in ♐ Sagittarius when the Moon has reached South declination of ∠-24.281° the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠24.238° at the point of next northern standstill on 23 November 2010 at 04:24 in ♊ Gemini.

Draconic month

4 days since the beginning of this draconic month in ♐ Sagittarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 7 days

In 7 days on 21 November 2010 at 17:27 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.
