Waxing Gibbous in Gemini

Waxing Gibbous on . Illuminated surface of the Moon is 91% and growing larger. Lunar cycle is 12 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is passing about ∠9° of ♊ Gemini tropical zodiac sector.

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 30 December 2003 at 10:03.

Wolf Moon after 3 days

Next Full Moon is the Wolf Moon of January 2004 after 3 days on 7 January 2004 at 15:40.

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 ∠1768"

Lunar disc appears visually 9.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1951".

Lunation 49 / 1002

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 49 of Meeus index or 1002 from Brown series.

Synodic month length 29.47 days

The length of this lunation is 29 days, 11 hours and 22 minutes and it is 51 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 1 hour and 22 minutes shorter than the mean synodic month length. It is 4 hours and 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠15.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠15.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠33.9°.

Moon after apogee

1 day since point of apogee on 3 January 2004 at 20:19 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 15 days until the Moon reaches the point of next perigee on 19 January 2004 at 19:25 in ♐ Sagittarius.

Distance to Moon 405 473 km

The Moon is 405 473 km (251 949 mi) away from Earth and getting closer over the next 15 days until the point perigee when Earth-Moon distance is going to be 362 768 km (225 414 mi).

Moon after ascending node

1 day after ascending node on 2 January 2004 at 20:11 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 16 January 2004 at 21:08 in ♏ Scorpio.

Moon before northern standstill

11 days since the last southern standstill on 23 December 2003 at 20:12 in ♑ Capricorn when the Moon has reached South declination of ∠-27.044° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠27.031° at the point of next northern standstill on 6 January 2004 at 21:36 in ♋ Cancer.

Draconic month

1 day since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 3 days

In 3 days on 7 January 2004 at 15:40 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.
