Last Quarter in Taurus

Last Quarter on . Illuminated surface of the Moon is 47% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 3 August 2010 at 04:59 UTC.

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♉ Taurus

Moon is passing about ∠14° of ♉ Taurus tropical zodiac sector.

Sturgeon Moon after 21 days

Next Full Moon is the Sturgeon Moon of August 2010 after 21 days on 24 August 2010 at 17:05.

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 ∠1836"

Lunar disc appears visually 3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1836" and ∠1891".

Lunation 130 / 1083

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 130 of Meeus index or 1083 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 28 minutes and it is 6 minutes longer 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 shorter than mean

The length of the current synodic month is 5 hours and 16 minutes shorter than the mean synodic month length. It is 53 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠332.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠332.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠349.5°.

Moon after apogee

5 days since point of apogee on 28 July 2010 at 23:50 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next perigee on 10 August 2010 at 17:56 in ♌ Leo.

Distance to Moon 390 439 km

The Moon is 390 439 km (242 608 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 357 858 km (222 363 mi).

Moon before descending node

10 days after ascending node on 24 July 2010 at 07:59 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following 4 days until the lunar crosses the ecliptic again from North to South in descending node on 7 August 2010 at 17:24 in ♋ Cancer.

Moon before northern standstill

12 days since the last southern standstill on 22 July 2010 at 11:12 in ♐ Sagittarius when the Moon has reached South declination of ∠-25.034° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠24.984° at the point of next northern standstill on 6 August 2010 at 02:49 in ♊ Gemini.

Draconic month

10 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 10 August 2010 at 03:08 in ♌ Leo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
