Moon phase and lunation details

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.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 18 January 2013 at 23:45.

Moon in ♊ Gemini

Moon is passing about ∠23° of ♊ Gemini tropical zodiac sector.

Upcoming main Moon phases

Wolf Moon after 3 days

Next Full Moon is the Wolf Moon of January after 3 days on 27 January 2013 at 04:38.

Apparent angular diameter ∠1769"

Lunar disc appears visually 9.72% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1949".

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 161 / 1114

Moon is 11 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.

Previous | Current lunation | Next

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.

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 lunation true anomaly is ∠23.3°. At the beginning of next synodic month true anomaly is ∠44.2°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

1 day after point of apogee on 22 January 2013 at 10:52, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 15 days until it gets to the point of perigee on 7 February 2013 at 12:09.

Distance to Moon 405 268 km

Moon is 405 268 km (251 822 mi) away from Earth on this date. At previous apogee point before 1 day, distance is 405 313 km (251 850 mi). Moon moves closer next 15 days until perigee, when Earth-Moon distance reaches 365 314 km (226 996 mi).

Moon after descending node

2 days after its descending node on 21 January 2013 at 01:19, the Moon follows the southern part of its orbit for the next 11 days untill it crosses the ecliptic from South to North in ascending node on 4 February 2013 at 02:14.

Draconic month

15 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon in northern standstill

At 05:12 on this date Moon meets its North standstill point and reaches northern declination of ∠20.816°. Next 13 days lunar orbit moves southward in opposite direction to face South declination of ∠-20.704° in its southern standstill point on 6 February 2013 at 00:27. This is the northernmost standstill for 2013.

Syzygy in 3 days

After 3 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 27 January 2013 at 04:38.
