Moon phase and lunation details

1 day after New Moon

Previous main lunar phase is the New Moon before 1 day on 18 December 2017 at 06:31.

Moonrise and moonset

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

Moon in ♑ Capricorn

Moon is passing about ∠11° of ♑ Capricorn tropical zodiac sector.

Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1950".

Wolf Moon after 13 days

Next Full Moon is the Wolf Moon of January 2018 after 13 days on 2 January 2018 at 02:24.

Upcoming main Moon phases

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 222 / 1175

The Moon is 1 day young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 222 of Meeus index or 1175 from Brown series.

Synodic month length 29.82 days

Length of current 222 lunation is 29 days, 19 hours and 47 minutes. This is the year's longest synodic month of 2017. It is 59 minutes longer than next lunation 223 length.

Lunation length longer than mean

Length of current synodic month is 7 hours and 3 minutes longer than the mean length of synodic month and it is the longest synodic month length of a for 21st century.

Lunar orbit position on

True anomaly ∠173.3°

This lunation true anomaly is ∠173.3°. At the beginning of next synodic month true anomaly will be ∠198.1°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon in apogee

Moon is reaching point of apogee on this date at 01:27, this is 14 days after last perigee on 4 December 2017 at 08:42 in ♊ Gemini. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 13 days ahead, until it will get to the point of next perigee on 1 January 2018 at 21:54 in ♋ Cancer.

Distance to Moon 406 605 km

This apogee Moon is 406 605 km (252 653 mi) away from Earth. This is the year's farthest apogee of 2017. It is 1 197 km farther than the mean apogee distance, but it is still 104 km closer than the farthest apogee of 21st century.

Moon before descending node

11 days after its ascending node on 8 December 2017 at 00:39 in ♌ Leo, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 22 December 2017 at 10:04 in ♒ Aquarius.

Moon in southern standstill

At 09:31 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-20.062°. This is the year's southernmost lunar standstill of 2017. Next 13 days the lunar orbit will move in opposite northward direction to face North declination of ∠20.055° in its northern standstill point on 2 January 2018 at 00:01 in ♋ Cancer.

Syzygy in 13 days

After 13 days on 2 January 2018 at 02:24 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
