Waxing Crescent in Libra

Waxing Crescent on . Illuminated surface of the Moon is 39% and growing larger. Lunar cycle is 6 days young.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♎ Libra

Moon is passing about ∠24° of ♎ Libra tropical zodiac sector.

6 days after New Moon

Previous main lunar phase is the New Moon before 6 days on 23 July 2017 at 09:46.

Sturgeon Moon after 9 days

Next Full Moon is the Sturgeon Moon of August 2017 after 9 days on 7 August 2017 at 18:11.

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 ∠1811"

Lunar disc appears visually 4.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1811" and ∠1890".

Lunation 217 / 1170

The Moon is 6 days young and navigating from the beginning to the first part of the current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.

Synodic month length 29.36 days

The length of this lunation is 29 days, 8 hours and 45 minutes and it is 2 hours and 15 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 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠27.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠27.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.5°.

Moon before apogee

7 days since point of perigee on 21 July 2017 at 17:09 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 4 days until the Moon reaches the point of next apogee on 2 August 2017 at 17:55 in ♐ Sagittarius.

Distance to Moon 395 808 km

The Moon is 395 808 km (245 944 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 026 km (251 671 mi).

Moon after ascending node

4 days after ascending node on 25 July 2017 at 00:46 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 8 August 2017 at 10:56 in ♒ Aquarius.

Moon before southern standstill

7 days since the last northern standstill on 21 July 2017 at 22:11 in ♋ Cancer when the Moon has reached North declination of ∠19.413° the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 4 August 2017 at 18:17 in ♑ Capricorn.

Draconic month

4 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 9 days

In 9 days on 7 August 2017 at 18:11 in ♒ Aquarius the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
