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 3 April 2017 at 18:39 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 in ♋ Cancer

Moon is passing about ∠10° of ♋ Cancer tropical zodiac sector.

Pink Moon after 7 days

Next Full Moon is the Pink Moon of April 2017 after 7 days on 11 April 2017 at 06:08.

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 ∠1955"

Lunar disc appears visually 1.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1955" and ∠1919".

Lunation 213 / 1166

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 213 of Meeus index or 1166 from Brown series.

Synodic month length 29.39 days

The length of this lunation is 29 days, 9 hours and 19 minutes and it is 1 hour and 51 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 3 hours and 25 minutes shorter than the mean synodic month length. It is 2 hours and 44 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠321.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠321.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠340.4°.

Moon after perigee

3 days since point of perigee on 30 March 2017 at 12:39 in ♉ Taurus the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next apogee on 15 April 2017 at 10:05 in ♐ Sagittarius.

Distance to Moon 366 585 km

The Moon is 366 585 km (227 785 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 405 478 km (251 952 mi).

Moon before ascending node

8 days after descending node on 25 March 2017 at 15:41 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 7 April 2017 at 09:14 in ♍ Virgo.

Moon at northern standstill

At 06:12 the Moon is meeting its standstill point to reach North declination of ∠18.984°. Over the upcoming 14 days the lunar orbit is going to tilt southward to face maximum declination of ∠-19.095° at the point of next southern standstill in ♑ Capricorn on 17 April 2017 at 13:12.

Draconic month

23 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 11 April 2017 at 06:08 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.
