Waning Crescent in Libra

Waning Crescent on . The illuminated surface of the moon is 2% and getting smaller. The lunar cycle is 28 days old.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠10° of ♎ Libra tropical zodiac sector.

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 12 October 2017 at 12:25.

Beaver Moon after 16 days

Next Full Moon is the Beaver Moon of November 2017 after 16 days on 4 November 2017 at 05:23.

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 ∠1847"

Lunar disc appears visually 4.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1847" and ∠1926".

Lunation 219 / 1172

The Moon is 28 days old and navigating from the second to the final part of the current synodic month. This is lunation 219 of Meeus index or 1172 from Brown series.

Synodic month length 29.57 days

The length of this lunation is 29 days, 13 hours and 42 minutes and it is 2 hours and 48 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 longer than mean

The length of the current synodic month is 58 minutes longer than the mean synodic month length. It is 6 hours and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠79°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠79° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠114.6°.

Moon before apogee

9 days since point of perigee on 9 October 2017 at 05:51 in ♊ Gemini 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 25 October 2017 at 02:25 in ♑ Capricorn.

Distance to Moon 388 160 km

The Moon is 388 160 km (241 191 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 405 151 km (251 749 mi).

Moon after ascending node

3 days after ascending node on 14 October 2017 at 22:10 in ♌ Leo the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 29 October 2017 at 06:41 in ♒ Aquarius.

Moon after northern standstill

6 days since the last northern standstill on 11 October 2017 at 18:21 in ♋ Cancer when the Moon has reached North declination of ∠19.616° the lunar orbit is extending southward over the next 7 days to face maximum declination of ∠-19.741° at the point of next southern standstill on 25 October 2017 at 18:13 in ♑ Capricorn.

Draconic month

3 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 1 day

In 1 day on 19 October 2017 at 19:12 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.
