Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 13 January 2015 at 09:47.

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.

Moon in ♐ Sagittarius

Moon is passing about ∠16° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1890"

Lunar disc appears visually 3.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1890" and ∠1950".

Snow Moon after 17 days

Next Full Moon is the Snow Moon of February 2015 after 17 days on 3 February 2015 at 23:09.

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 185 / 1138

The Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 185 of Meeus index or 1138 from Brown series.

Synodic month length 29.48 days

The length of the lunation is 29 days, 11 hours and 38 minutes. It is 1 hour and 4 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 shorter than mean

The length of the current synodic month is 1 hour and 6 minutes shorter than the mean synodic month length. It is 5 hours and 3 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠318°

At the beginning of the lunation cycle the true anomaly is ∠318°. At the beginning of next synodic month the true anomaly is going to be ∠338.3°.

Moon before apogee

7 days after point of apogee on 9 January 2015 at 18:17 in ♍ Virgo. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 4 days, until the Moon reaches the point of next perigee on 21 January 2015 at 20:06 in ♒ Aquarius.

Previous apogeeNext perigee

Distance to Moon 379 257 km

The Moon is 379 257 km (235 659 mi) away from Earth and getting closer over the next 4 days until the point perigee when Earth-Moon distance is going to be 359 643 km (223 472 mi).

Moon after ascending node

4 days after ascending node on 12 January 2015 at 15:33 in ♎ Libra. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 25 January 2015 at 10:23 in ♈ Aries.

Draconic month

4 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

13 days since the previous standstill on 3 January 2015 at 17:53 in ♊ Gemini when the Moon has reached North declination of ∠18.650°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-18.577° at the point of next southern standstill on 18 January 2015 at 06:17 in ♐ Sagittarius.

Syzygy in 3 days

In 3 days on 20 January 2015 at 13:14 in ♑ Capricorn 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.
