Waning Crescent in Libra

Waning Crescent on . Illuminated surface of the Moon is 4% and getting smaller. Lunar cycle is 27 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 is entering ♎ Libra

Moon is passing first ∠1° of ♎ Libra tropical zodiac sector.

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 11 October 2009 at 08:56.

Beaver Moon after 17 days

Next Full Moon is the Beaver Moon of November 2009 after 17 days on 2 November 2009 at 19:14.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1922"

Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1925".

Lunation 120 / 1073

The Moon is 27 days old and navigating from the second to the final part of the current synodic month. This is lunation 120 of Meeus index or 1073 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 49 minutes and it is 2 hours 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 1 hour and 55 minutes shorter than the mean synodic month length. It is 4 hours and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠39.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠39.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠65.2°.

Moon after perigee

2 days since point of perigee on 13 October 2009 at 12:28 in ♌ Leo the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 25 October 2009 at 23:18 in ♑ Capricorn.

Distance to Moon 372 954 km

The Moon is 372 954 km (231 743 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 404 168 km (251 138 mi).

Moon after descending node

4 days after descending node on 11 October 2009 at 23:01 in ♋ Cancer the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 25 October 2009 at 08:52 in ♑ Capricorn.

Moon before southern standstill

7 days since the last northern standstill on 9 October 2009 at 09:49 in ♊ Gemini when the Moon has reached North declination of ∠26.057° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-25.951° at the point of next southern standstill on 22 October 2009 at 12:10 in ♐ Sagittarius.

Draconic month

18 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 1 day

In 1 day on 18 October 2009 at 05:33 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.
