Moon phase and lunation details
5 days after First Quarter
Previous main lunar phase is the First Quarter before 5 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.
Moon is entering ♊ Gemini
Moon is passing first ∠3° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1801"
Lunar disc appears visually 7.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1950".
Cold Moon after 1 day
Next Full Moon is the Cold Moon of December 2013 after 1 day on 17 December 2013 at 09:28.
Upcoming main Moon phases
- Full Moon in Gemini ♊ on 17 December 2013 at 09:28
- Last Quarter in Virgo ♍ on 25 December 2013 at 13:48
- New Moon in Capricorn ♑ on 1 January 2014 at 11:14
- First Quarter in Aries ♈ on 8 January 2014 at 03:39
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 172 / 1125
The 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 172 of Meeus index or 1125 from Brown series.
Synodic month length 29.45 days
Length of current 172 lunation is 29 days, 10 hours and 52 minutes. This is the year's shortest synodic month of 2013. It is 28 minutes longer than next lunation 173 length.
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 will be ∠353°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
Moon before apogee
11 days after point of perigee on 4 December 2013 at 10:15 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 4 days, until it get to the point of next apogee on 19 December 2013 at 23:49 in ♋ Cancer.
Distance to Moon 397 961 km
Moon is 397 961 km (247 282 mi) away from Earth on this date. Moon moves farther next 4 days until apogee, when Earth-Moon distance will reach 406 269 km (252 444 mi).
Moon after descending node
2 days after its descending node on 13 December 2013 at 10:10 in ♉ Taurus, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 28 December 2013 at 00:21 in ♏ Scorpio.
Draconic month
14 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.
Moon before northern standstill
11 days after previous South standstill on 3 December 2013 at 16:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-19.552°. Next day the lunar orbit moves northward to face North declination of ∠19.570° in the next northern standstill on 17 December 2013 at 01:00 in ♊ Gemini.
Syzygy in 1 day
After 1 day on 17 December 2013 at 09:28 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
