Waning Crescent in Cancer

Waning Crescent on . Illuminated surface of the Moon is 21% and getting smaller. Lunar cycle is 25 days old.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♋ Cancer

Moon is passing about ∠17° of ♋ Cancer tropical zodiac sector.

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 1 September 2010 at 17:22.

Harvest Moon after 18 days

Next Full Moon is the Harvest Moon of September 2010 after 18 days on 23 September 2010 at 09:17.

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 ∠1937"

Lunar disc appears visually 1.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1937" and ∠1903".

Lunation 131 / 1084

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 131 of Meeus index or 1084 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 22 minutes and it is 53 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2010. 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 shorter than mean

The length of the current synodic month is 5 hours and 22 minutes shorter than the mean synodic month length. It is 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠349.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠349.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠4.6°.

Moon before perigee

10 days since point of apogee on 25 August 2010 at 05:51 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 8 September 2010 at 04:00 in ♍ Virgo.

Distance to Moon 370 081 km

The Moon is 370 081 km (229 958 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 357 193 km (221 949 mi).

Moon in descending node

Moon is in descending node in ♋ Cancer at 00:16 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 12 days until Moon's next ascending node later on 16 September 2010 at 13:56 in ♑ Capricorn.

Moon after northern standstill

2 days since the last northern standstill on 2 September 2010 at 11:20 in ♊ Gemini when the Moon has reached North declination of ∠24.807° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-24.710° at the point of next southern standstill on 14 September 2010 at 23:47 in ♐ Sagittarius.

Draconic month

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

Syzygy in 3 days

In 3 days on 8 September 2010 at 10:30 in ♍ Virgo 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.
