Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is passing about ∠18° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1971"

Wolf Moon after 6 days

Next Full Moon is the Wolf Moon of January 2007 after 6 days on 3 January 2007 at 13:57.

Upcoming main Moon phases

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 86 of Meeus index or 1039 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.58 days

Length of current 86 lunation is 29 days, 14 hours and 1 minute. It is 1 hour and 46 minutes longer than next lunation 87 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 16 minutes longer than the mean length of synodic month, but it is still 5 hours and 47 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠276.5°

This lunation true anomaly is ∠276.5°. At the beginning of next synodic month true anomaly will be ∠308.6°. 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 perigee

Moon is reaching point of perigee on this date at 01:48, this is 14 days after last apogee on 13 December 2006 at 18:55 in ♍ Virgo. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 13 days ahead, until it will get to the point of next apogee on 10 January 2007 at 16:26 in ♎ Libra.

Distance to Moon 370 321 km

This perigee Moon is 370 321 km (230 107 mi) away from Earth. This is the year's farthest perigee of 2006. It is 7 813 km closer than the mean perigee distance, but it is still 35 km farther than the closest perigee of 21st century.

Moon after ascending node

2 days after its ascending node on 26 December 2006 at 10:36 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 8 January 2007 at 17:44 in ♍ Virgo.

Moon before northern standstill

7 days after previous South standstill on 20 December 2006 at 13:40 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.378°. Next 4 days the lunar orbit moves northward to face North declination of ∠28.396° in the next northern standstill on 2 January 2007 at 11:57 in ♊ Gemini.

Syzygy in 6 days

After 6 days on 3 January 2007 at 13:57 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
