Moon phase and lunation details
3 days after First Quarter
Previous main lunar phase is the First Quarter before 3 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 ∠11° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1768"
Lunar disc appears visually 9.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1949".
Wolf Moon after 4 days
Next Full Moon is the Wolf Moon of January 2013 after 4 days on 27 January 2013 at 04:38.
Upcoming main Moon phases
- Full Moon in Leo ♌ on 27 January 2013 at 04:38
- Last Quarter in Scorpio ♏ on 3 February 2013 at 13:56
- New Moon in Aquarius ♒ on 10 February 2013 at 07:20
- First Quarter in Taurus ♉ on 17 February 2013 at 20:31
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 10 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.
Synodic month length 29.48 days
The length of the lunation is 29 days, 11 hours and 36 minutes. It is 55 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
Lunation length shorter than mean
The length of the current synodic month is 1 hour and 8 minutes shorter than the mean synodic month length. It is 5 hours and 1 minute longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠23.3°
At the beginning of the lunation cycle the true anomaly is ∠23.3°. At the beginning of next synodic month the true anomaly is going to be ∠44.2°.
Moon at apogee
Moon is at apogee at 10:52. It is 12 days after previous perigee on 10 January 2013 at 10:26 in ♑ Capricorn. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 16 days, until point of next perigee on 7 February 2013 at 12:09 in ♑ Capricorn.
Distance to Moon 405 313 km
This apogee Moon is 405 313 km (251 850 mi) away from Earth. It is 95 km further than the mean apogee distance, but it is still 1 396 km closer than the farthest apogee of 21st century.
Moon after descending node
1 day after descending node on 21 January 2013 at 01:19 in ♉ Taurus. The Moon is located south of the ecliptic over the following 12 days, until the lunar orbit crosses from South to North in ascending node on 4 February 2013 at 02:14 in ♏ Scorpio.
Draconic month
14 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the second to the final part of the cycle.
Moon before northern standstill
12 days since the previous standstill on 9 January 2013 at 15:22 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.879°, the lunar orbit is extending northward over the next day to face maximum declination of ∠20.816° at the point of next northern standstill on 23 January 2013 at 05:12 in ♊ Gemini.
Syzygy in 4 days
In 4 days on 27 January 2013 at 04:38 in ♌ Leo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
