Waning Crescent in Cancer

Waning Crescent on . Illuminated surface of the Moon is 35% and getting smaller. Lunar cycle is 23 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 leaving the last ∠4° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 1 October 2010 at 03:52.

Hunter Moon after 20 days

Next Full Moon is the Hunter Moon of October 2010 after 20 days on 23 October 2010 at 01:36.

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 ∠1945"

Lunar disc appears visually 1.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1917".

Lunation 132 / 1085

The Moon is 23 days old and navigating from the second to the final part of the current synodic month. This is lunation 132 of Meeus index or 1085 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 15 minutes and it is 1 hour and 52 minutes shorter than the upcoming lunation's length. 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 4 hours and 29 minutes shorter than the mean synodic month length. It is 1 hour and 40 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠4.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠4.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠20.4°.

Moon before perigee

11 days since point of apogee on 21 September 2010 at 08:03 in ♓ Pisces the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 4 days until the Moon reaches the point of next perigee on 6 October 2010 at 13:41 in ♍ Virgo.

Distance to Moon 368 572 km

The Moon is 368 572 km (229 020 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 359 453 km (223 354 mi).

Moon after descending node

1 day after descending node on 1 October 2010 at 02:42 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from South to North in ascending node on 13 October 2010 at 15:36 in ♐ Sagittarius.

Moon after northern standstill

2 days since the last northern standstill on 29 September 2010 at 17:37 in ♊ Gemini when the Moon has reached North declination of ∠24.555° the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-24.457° at the point of next southern standstill on 12 October 2010 at 07:49 in ♐ Sagittarius.

Draconic month

15 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 5 days

In 5 days on 7 October 2010 at 18:44 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.
