Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♍ Virgo

Moon is passing about ∠22° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1821"

Lunar disc appears visually 6.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1821" and ∠1950".

Wolf Moon after 22 days

Next Full Moon is the Wolf Moon of January 2017 after 22 days on 12 January 2017 at 11:34.

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 209 / 1162

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 209 of Meeus index or 1162 from Brown series.

Synodic month length 29.77 days

Length of current 209 lunation is 29 days, 18 hours and 35 minutes. It is 1 hour and 21 minutes longer than next lunation 210 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 51 minutes longer than the mean length of synodic month, but it is still 1 hour and 12 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠194.9°

This lunation true anomaly is ∠194.9°. At the beginning of next synodic month true anomaly will be ∠223.4°. 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 before apogee

7 days after point of perigee on 12 December 2016 at 23:27 in ♉ Taurus. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 4 days, until it get to the point of next apogee on 25 December 2016 at 05:55 in ♏ Scorpio.

Distance to Moon 393 569 km

Moon is 393 569 km (244 552 mi) away from Earth on this date. Moon moves farther next 4 days until apogee, when Earth-Moon distance will reach 405 870 km (252 196 mi).

Moon after ascending node

1 day after its ascending node on 19 December 2016 at 04:46 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 13 days, until it will cross the ecliptic from North to South in descending node on 2 January 2017 at 18:14 in ♒ Aquarius.

Moon after northern standstill

5 days after previous North standstill on 14 December 2016 at 21:43 in ♊ Gemini, when Moon has reached northern declination of ∠18.937°. Next 8 days the lunar orbit moves southward to face South declination of ∠-18.958° in the next southern standstill on 29 December 2016 at 03:30 in ♑ Capricorn.

Syzygy in 8 days

After 8 days on 29 December 2016 at 06:53 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
