Waning Crescent in Leo

Waning Crescent on . Illuminated surface of the Moon is 9% and getting smaller. Lunar cycle is 26 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 ♌ Leo

Moon is passing about ∠6° of ♌ Leo tropical zodiac sector.

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 28 August 2013 at 09:35.

Harvest Moon after 16 days

Next Full Moon is the Harvest Moon of September 2013 after 16 days on 19 September 2013 at 11:13.

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 ∠1779"

Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1779" and ∠1902".

Lunation 168 / 1121

The Moon is 26 days old and navigating from the second to the final part of the current synodic month. This is lunation 168 of Meeus index or 1121 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 45 minutes and it is 47 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 longer than mean

The length of the current synodic month is 1 hour and 1 minute longer than the mean synodic month length. It is 6 hours and 2 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠216.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠216.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠249.2°.

Moon after apogee

2 days since point of apogee on 30 August 2013 at 23:46 in ♋ Cancer the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next perigee on 15 September 2013 at 16:34 in ♑ Capricorn.

Distance to Moon 402 944 km

The Moon is 402 944 km (250 378 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 367 388 km (228 284 mi).

Moon after descending node

7 days after descending node on 26 August 2013 at 08:19 in ♉ Taurus the Moon is positioned south of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from South to North in ascending node on 9 September 2013 at 17:29 in ♏ Scorpio.

Moon after northern standstill

3 days since the last northern standstill on 29 August 2013 at 17:03 in ♊ Gemini when the Moon has reached North declination of ∠19.801° the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-19.685° at the point of next southern standstill on 12 September 2013 at 18:30 in ♐ Sagittarius.

Draconic month

19 days since the beginning of this draconic month in ♏ Scorpio the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 2 days

In 2 days on 5 September 2013 at 11:36 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.
