Waxing Gibbous 86% illuminated

Waxing Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 86% and growing larger.

Previous date | Moon Today | Next date

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 9 December 2013 at 15:12.

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 ∠1839"

Lunar disc appears visually 5.83% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1839" and ∠1949".

Cold Moon after 3 days

Next Full Moon is the Cold Moon of December after 3 days on 17 December 2013 at 09:28.

Moon in Taurus

Moon is passing about ∠8° of Taurus tropical zodiac sector.

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.

Upcoming Moon phases

Synodic month details

Lunation 172 / 1125

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 172 of Meeus index or 1125 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.45 days

Length of current 172 lunation is 29 days, 10 hours and 52 minutes. It is 28 minutes longer than next lunation 173. This is the shortest synodic month of 2013.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 52 minutes shorter than the mean length of synodic month, but it is still 4 hours and 17 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠336.4°

This lunation true anomaly is ∠336.4°. At the beginning of next synodic month true anomaly is ∠353°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon before apogee

9 days after point of perigee on 4 December 2013 at 10:15, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 6 days until it gets to the point of apogee on 19 December 2013 at 23:49.

Distance to Moon 389 816 km

Moon is 389 816 km (242 220 mi) away from Earth on this date. At previous perigee point before 9 days, distance is 360 065 km (223 734 mi). Moon moves farther next 6 days until apogee, when Earth-Moon distance reaches 406 269 km (252 444 mi).

Moon in descending node

Moon is in descending node at 10:10 on this date, it crosses the ecliptic from South to North. Moon follows the southern part of its orbit for the next 14 days to meet ascending node on 28 December 2013 at 00:21.

Draconic month

12 days after its beginning, the Moon is moving through the middle part of current draconic month.

Previous | Next

Moon before northern standstill

9 days after previous South standstill on 3 December 2013 at 16:38, when Moon reaches southern declination of ∠-19.552°, lunar orbit moves northward for the next 3 days to face North declination of ∠19.570° in the next northern standstill on 17 December 2013 at 01:00.

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 17 December 2013 at 09:28.
