Waxing Gibbous in Gemini

Waxing Gibbous on . The illuminated surface of the moon is 89% and growing larger. The lunar cycle is 11 days young.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon in ♊ Gemini

Moon is leaving the last ∠1° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 23 January 2010 at 10:53.

Wolf Moon after 2 days

Next Full Moon is the Wolf Moon of January 2010 after 2 days on 30 January 2010 at 06:18.

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 ∠1944"

Lunar disc appears visually 0.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1944" and ∠1948".

Lunation 124 / 1077

The Moon is 11 days young and navigating from the first to the middle part of the current synodic month. This is lunation 124 of Meeus index or 1077 from Brown series.

Synodic month length 29.82 days

The length of this lunation is 29 days, 19 hours and 40 minutes and it is 1 hour and 30 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2010. 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 6 hours and 56 minutes longer than the mean synodic month length. It is 7 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠164.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠164.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠188.9°.

Moon before perigee

10 days since point of apogee on 17 January 2010 at 01:40 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 30 January 2010 at 09:03 in ♌ Leo.

Distance to Moon 368 628 km

The Moon is 368 628 km (229 055 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 356 593 km (221 577 mi).

Moon before descending node

12 days after ascending node on 14 January 2010 at 23:18 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 29 January 2010 at 00:02 in ♋ Cancer.

Moon after northern standstill

1 day since the last northern standstill on 26 January 2010 at 21:04 in ♊ Gemini when the Moon has reached North declination of ∠25.783° the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-25.749° at the point of next southern standstill on 8 February 2010 at 14:27 in ♐ Sagittarius.

Draconic month

12 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 2 days

In 2 days on 30 January 2010 at 06:18 in ♌ Leo 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.
