Moon phase and lunation details

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 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 ♊ Gemini

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

Apparent angular diameter ∠1769"

Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1949".

Wolf Moon after 3 days

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

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 161 / 1114

The 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.

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 after apogee

1 day after point of apogee on 22 January 2013 at 10:52 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 15 days, until it get to the point of next perigee on 7 February 2013 at 12:09 in ♑ Capricorn.

Previous apogeeNext perigee

Distance to Moon 405 268 km

Moon is 405 268 km (251 822 mi) away from Earth on this date. Moon moves closer next 15 days until perigee, when Earth-Moon distance will reach 365 314 km (226 996 mi).

Moon after descending node

2 days after its descending node on 21 January 2013 at 01:19 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 11 days, until it will cross the ecliptic from South to North in ascending node on 4 February 2013 at 02:14 in ♏ Scorpio.

Draconic month

15 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.

Moon in northern standstill

At 05:12 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠20.816°. This is the year's northernmost lunar standstill of 2013. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-20.704° in its southern standstill point on 6 February 2013 at 00:27 in ♐ Sagittarius.

Syzygy in 3 days

After 3 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.
