Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 12 January 2011 at 11:31.

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.

Moon in ♊ Gemini

Moon is leaving the last ∠4° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1877"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1877" and ∠1950".

Wolf Moon after 2 days

Next Full Moon is the Wolf Moon of January 2011 after 2 days on 19 January 2011 at 21:21.

Upcoming main Moon phases

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.

Lunation 136 / 1089

The Moon is 12 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 136 of Meeus index or 1089 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.73 days

Length of current 136 lunation is 29 days, 17 hours and 28 minutes. It is 47 minutes shorter than next lunation 137 length.

Lunation length longer than mean

Length of current synodic month is 4 hours and 44 minutes longer than the mean length of synodic month, but it is still 2 hours and 19 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠103.5°

This New Moon true anomaly is ∠103.5°. At beginning of next synodic month true anomaly will be ∠139.2°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before perigee

7 days after point of apogee on 10 January 2011 at 05:38 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 22 January 2011 at 00:10 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 381 979 km

Moon is 381 979 km (237 351 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 362 793 km (225 429 mi).

Moon before descending node

13 days after its ascending node on 3 January 2011 at 12:48 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 18 January 2011 at 00:06 in ♋ Cancer.

Draconic month

13 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the first to the middle part of it.

Moon after northern standstill

1 day after previous North standstill on 16 January 2011 at 22:51 in ♊ Gemini, when Moon has reached northern declination of ∠24.221°. Next 12 days the lunar orbit moves southward to face South declination of ∠-24.180° in the next southern standstill on 29 January 2011 at 16:26 in ♐ Sagittarius.

Syzygy in 2 days

After 2 days on 19 January 2011 at 21:21 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
