First Quarter in Cancer

First Quarter on . Illuminated surface of the Moon is 47% and growing larger. Lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 30 March 2012 at 19:41 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 ♋ Cancer

Moon is passing about ∠7° of ♋ Cancer tropical zodiac sector.

Pink Moon after 7 days

Next Full Moon is the Pink Moon of April 2012 after 7 days on 6 April 2012 at 19:19.

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 ∠1811"

Lunar disc appears visually 5.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1921".

Lunation 151 / 1104

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 151 of Meeus index or 1104 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 41 minutes and it is 12 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2012. 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 longer than mean

The length of the current synodic month is 3 hours and 57 minutes longer than the mean synodic month length. It is 3 hours and 6 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠142.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠142.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠168.7°.

Moon after apogee

4 days since point of apogee on 26 March 2012 at 06:04 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 8 days until the Moon reaches the point of next perigee on 7 April 2012 at 16:59 in ♎ Libra.

Distance to Moon 395 845 km

The Moon is 395 845 km (245 967 mi) away from Earth and getting closer over the next 8 days until the point perigee when Earth-Moon distance is going to be 358 314 km (222 646 mi).

Moon after descending node

2 days after descending node on 28 March 2012 at 00:19 in ♊ Gemini the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 10 April 2012 at 00:47 in ♐ Sagittarius.

Moon after northern standstill

1 day since the last northern standstill on 28 March 2012 at 23:40 in ♊ Gemini when the Moon has reached North declination of ∠21.890° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-21.814° at the point of next southern standstill on 10 April 2012 at 21:03 in ♐ Sagittarius.

Draconic month

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

Syzygy in 7 days

In 7 days on 6 April 2012 at 19:19 in ♎ Libra 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.
