Waning Crescent in Sagittarius

Waning Crescent on . Illuminated surface of the Moon is 19% and getting smaller. Lunar cycle is 25 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 ♐ Sagittarius

Moon is passing about ∠13° of ♐ Sagittarius tropical zodiac sector.

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 19 January 2017 at 22:14.

Snow Moon after 18 days

Next Full Moon is the Snow Moon of February 2017 after 18 days on 11 February 2017 at 00:33.

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 ∠1771"

Lunar disc appears visually 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1949".

Lunation 210 / 1163

The Moon is 25 days old and navigating from the second to the final part of the current synodic month. This is lunation 210 of Meeus index or 1163 from Brown series.

Synodic month length 29.72 days

The length of this lunation is 29 days, 17 hours and 14 minutes and it is 2 hours and 23 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 4 hours and 30 minutes longer than the mean synodic month length. It is 2 hours and 33 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠223.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠223.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠259.5°.

Moon after apogee

1 day since point of apogee on 22 January 2017 at 00:14 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 14 days until the Moon reaches the point of next perigee on 6 February 2017 at 13:59 in ♊ Gemini.

Distance to Moon 404 692 km

The Moon is 404 692 km (251 464 mi) away from Earth and getting closer over the next 14 days until the point perigee when Earth-Moon distance is going to be 368 817 km (229 172 mi).

Moon before descending node

8 days after ascending node on 15 January 2017 at 10:45 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from North to South in descending node on 29 January 2017 at 22:21 in ♒ Aquarius.

Moon before southern standstill

12 days since the last northern standstill on 11 January 2017 at 09:32 in ♋ Cancer when the Moon has reached North declination of ∠18.932° the lunar orbit is extending southward over the next day to face maximum declination of ∠-18.900° at the point of next southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn.

Draconic month

8 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 4 days

In 4 days on 28 January 2017 at 00:07 in ♒ Aquarius 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.
