Previous date | Moon Today | Next date

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 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.

Apparent angular diameter ∠1783"

Lunar disc appears visually 8.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1783" and ∠1949".

Wolf Moon after 1 day

Next Full Moon is the Wolf Moon of January after 1 day on 27 January 2013 at 04:38.

Moon in Cancer

Moon is passing about ∠16° of Cancer tropical zodiac sector.

Upcoming Moon phases

Lunar orbit details for

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 161 / 1114

Moon is 13 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.

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

3 days 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 13 days until it gets to the point of perigee on 7 February 2013 at 12:09.

Distance to Moon 402 060 km

Moon is 402 060 km (249 829 mi) away from Earth on this date. At previous apogee point before 3 days, distance is 405 313 km (251 850 mi). Moon moves closer next 13 days until perigee, when Earth-Moon distance reaches 365 314 km (226 996 mi).

Moon after descending node

4 days after its descending node on 21 January 2013 at 01:19, the Moon follows the southern part of its orbit for the next 9 days untill it crosses the ecliptic from South to North in ascending node on 4 February 2013 at 02:14.

Draconic month

17 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 after northern standstill

2 days after previous North standstill on 23 January 2013 at 05:12, when Moon reaches northern declination of ∠20.816°, lunar orbit moves southward for the next 11 days to face South declination of ∠-20.704° in the next southern standstill on 6 February 2013 at 00:27.

Syzygy in 1 day

After 1 day 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.
