Last Quarter in Cancer

Last Quarter on . Illuminated surface of the Moon is 44% and getting smaller. Lunar cycle is 22 days old.

* The exact date and time of this Last Quarter phase is on 4 October 2015 at 21:06 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 ♋ Cancer

Moon is passing about ∠19° of ♋ Cancer tropical zodiac sector.

Hunter Moon after 22 days

Next Full Moon is the Hunter Moon of October 2015 after 22 days on 27 October 2015 at 12:05.

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 ∠1844"

Lunar disc appears visually 4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1844" and ∠1919".

Lunation 194 / 1147

The Moon is 22 days old and navigating through the last part of the current synodic month. This is lunation 194 of Meeus index or 1147 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 24 minutes and it is 17 minutes shorter 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 longer than mean

The length of the current synodic month is 4 hours and 40 minutes longer than the mean synodic month length. It is 2 hours and 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠169.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠169.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠192.9°.

Moon before apogee

7 days since point of perigee on 28 September 2015 at 01:46 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 11 October 2015 at 13:17 in ♍ Virgo.

Distance to Moon 388 799 km

The Moon is 388 799 km (241 588 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 389 km (252 518 mi).

Moon before ascending node

7 days after descending node on 27 September 2015 at 21:04 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 October 2015 at 10:54 in ♎ Libra.

Moon after northern standstill

1 day since the last northern standstill on 3 October 2015 at 23:55 in ♊ Gemini when the Moon has reached North declination of ∠18.140° the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-18.190° at the point of next southern standstill on 18 October 2015 at 18:31 in ♐ Sagittarius.

Draconic month

21 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 7 days

In 7 days on 13 October 2015 at 00:06 in ♎ Libra 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.
