Moon phase and lunation details

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 11 December 2015 at 10:29.

Moonrise and moonset

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

Moon in ♒ Aquarius

Moon is passing about ∠13° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1922"

Lunar disc appears visually 1.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1950".

Cold Moon after 9 days

Next Full Moon is the Cold Moon of December 2015 after 9 days on 25 December 2015 at 11:11.

Upcoming main Moon phases

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.

Lunation 197 / 1150

The Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 197 of Meeus index or 1150 from Brown series.

Synodic month length 29.63 days

The length of the lunation is 29 days, 15 hours and 1 minute. It is 1 hour and 53 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 2 hours and 17 minutes longer than the mean synodic month length. It is 4 hours and 46 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠255.6°

At the beginning of the lunation cycle the true anomaly is ∠255.6°. At the beginning of next synodic month the true anomaly is going to be ∠292.2°.

Moon before apogee

9 days after point of apogee on 5 December 2015 at 14:56 in ♎ Libra. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 21 December 2015 at 08:53 in ♉ Taurus.

Previous apogeeNext perigee

Distance to Moon 372 980 km

The Moon is 372 980 km (231 759 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 368 418 km (228 924 mi).

Moon before descending node

10 days after ascending node on 4 December 2015 at 18:33 in ♍ Virgo. The Moon is located north of the ecliptic over the following 3 days, until the lunar orbit crosses from North to South in descending node on 18 December 2015 at 15:13 in ♓ Pisces.

Previous nodeNext node

Draconic month

10 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

3 days since the previous standstill on 12 December 2015 at 08:15 in ♑ Capricorn when the Moon has reached South declination of ∠-18.438°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠18.444° at the point of next northern standstill on 25 December 2015 at 07:30 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 9 days

In 9 days on 25 December 2015 at 11:11 in ♋ Cancer 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.
