First Quarter in Aries

First Quarter on . The illuminated surface of the moon is 60% and growing larger. The lunar cycle is 8 days young.

* The exact date and time of this First Quarter phase is on 27 December 2006 at 14:48 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon in ♈ Aries

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

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.

Moderate tide

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.

Apparent angular diameter ∠1971"

Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1951".

Lunation 86 / 1039

The Moon is 8 days young and navigating through the first part of the current synodic month. This is lunation 86 of Meeus index or 1039 from Brown series.

Synodic month length 29.58 days

The length of this lunation is 29 days, 14 hours and 1 minute and it is 1 hour and 46 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 16 minutes longer than the mean synodic month length. It is 5 hours and 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠276.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠276.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠308.6°.

Moon at perigee

Moon is at perigee at 01:48 about 14 days since last apogee on 13 December 2006 at 18:55 in ♍ Virgo the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 13 days until 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 further than the closest perigee of 21st century.

Moon after ascending node

2 days after ascending node on 26 December 2006 at 10:36 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 11 days until the lunar crosses the ecliptic again from North to South in descending node on 8 January 2007 at 17:44 in ♍ Virgo.

Moon before northern standstill

7 days since the last southern standstill on 20 December 2006 at 13:40 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.378° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.396° at the point of next northern standstill on 2 January 2007 at 11:57 in ♊ Gemini.

Draconic month

2 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 6 days

In 6 days on 3 January 2007 at 13:57 in ♋ Cancer the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
