Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 18 January 2013 at 23:45.

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 ♉ Taurus

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

Lunar disc appears visually 9.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1950".

Wolf Moon after 5 days

Next Full Moon is the Wolf Moon of January 2013 after 5 days on 27 January 2013 at 04:38.

Upcoming main Moon phases

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 161 / 1114

The Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 161 of Meeus index or 1114 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.48 days

Length of current 161 lunation is 29 days, 11 hours and 36 minutes. It is 55 minutes shorter than next lunation 162 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 8 minutes shorter than the mean length of synodic month, but it is still 5 hours and 1 minute longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠23.3°

This New Moon true anomaly is ∠23.3°. At beginning of next synodic month true anomaly will be ∠44.2°. 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 apogee

11 days after point of perigee on 10 January 2013 at 10:26 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 22 January 2013 at 10:52 in ♊ Gemini.

Distance to Moon 404 678 km

Moon is 404 678 km (251 455 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 313 km (251 850 mi).

Moon in descending node

Moon is in descending node in ♉ Taurus at 01:19 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 4 February 2013 at 02:14 in ♏ Scorpio.

Moon before northern standstill

11 days after previous South standstill on 9 January 2013 at 15:22 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.879°. Next day the lunar orbit moves northward to face North declination of ∠20.816° in the next northern standstill on 23 January 2013 at 05:12 in ♊ Gemini.

Syzygy in 5 days

After 5 days on 27 January 2013 at 04:38 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
