Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 25 January 2005 at 10:32.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♎ Libra

Moon is passing about ∠20° of ♎ Libra tropical zodiac sector.

Apparent angular diameter ∠1869"

Lunar disc appears visually 4.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1869" and ∠1947".

Wolf Moon before 6 days

Next Full Moon is the Snow Moon of February 2005 after 23 days on 24 February 2005 at 04:54.

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 62 / 1015

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 62 of Meeus index or 1015 from Brown series.

Synodic month length 29.43 days

The length of the lunation is 29 days, 10 hours and 25 minutes. This is the year's shortest synodic month of 2005. It is 17 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 2 hours and 19 minutes shorter than the mean synodic month length. It is 3 hours and 50 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠1.4°

At the beginning of the lunation cycle the true anomaly is ∠1.4°. At the beginning of next synodic month the true anomaly is going to be ∠17.1°.

Moon before apogee

7 days after point of apogee on 23 January 2005 at 18:54 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 7 days, until the Moon reaches the point of next perigee on 7 February 2005 at 22:09 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 383 573 km

The Moon is 383 573 km (238 341 mi) away from Earth and getting closer over the next 7 days until the point perigee when Earth-Moon distance is going to be 358 564 km (222 801 mi).

Moon in descending node

Moon is in descending node in ♎ Libra at 22:49 crossing the ecliptic from North to South to meet ascending node 12 days later on 13 February 2005 at 10:25 in ♈ Aries.

Previous nodeNext node

Draconic month

14 days since the beginning of current draconic month in ♈ Aries, the Moon is navigating from the second to the final part of the cycle.

Moon before southern standstill

8 days since the previous standstill on 22 January 2005 at 19:22 in ♊ Gemini when the Moon has reached North declination of ∠27.973°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-28.071° at the point of next southern standstill on 5 February 2005 at 21:10 in ♐ Sagittarius.

Syzygy in 8 days

In 8 days on 8 February 2005 at 22:28 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.
