Moon phase and lunation details
5 days after Full Moon
Previous main lunar phase is the Full Moon before 5 days on 12 January 2017 at 11:34.
Moonrise and moonset
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon is entering ♎ Libra
Moon is passing first ∠0° of ♎ Libra tropical zodiac sector.
Apparent angular diameter ∠1814"
Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1814" and ∠1950".
Wolf Moon before 5 days
Next Full Moon is the Snow Moon of February 2017 after 24 days on 11 February 2017 at 00:33.
Upcoming main Moon phases
- Last Quarter in Libra ♎ on 19 January 2017 at 22:14
- New Moon in Aquarius ♒ on 28 January 2017 at 00:07
- First Quarter in Taurus ♉ on 4 February 2017 at 04:19
- Full Moon in Leo ♌ on 11 February 2017 at 00:33
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.
Lunation 210 / 1163
The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 210 of Meeus index or 1163 from Brown series.
Synodic month length 29.72 days
Length of current 210 lunation is 29 days, 17 hours and 14 minutes. It is 2 hours and 23 minutes longer than next lunation 211 length.
Lunation length longer than mean
Length of current synodic month is 4 hours and 30 minutes longer than the mean length of synodic month, but it is still 2 hours and 33 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠223.4°
This lunation true anomaly is ∠223.4°. At the beginning of next synodic month true anomaly will be ∠259.5°. 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
7 days after point of perigee on 10 January 2017 at 06:07 in ♊ Gemini. 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 22 January 2017 at 00:14 in ♐ Sagittarius.
Distance to Moon 395 044 km
Moon is 395 044 km (245 469 mi) away from Earth on this date. Moon moves farther next 4 days until apogee, when Earth-Moon distance will reach 404 913 km (251 601 mi).
Moon after ascending node
2 days after its ascending node on 15 January 2017 at 10:45 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 29 January 2017 at 22:21 in ♒ Aquarius.
Draconic month
2 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.
Moon after northern standstill
6 days after previous North standstill on 11 January 2017 at 09:32 in ♋ Cancer, when Moon has reached northern declination of ∠18.932°. Next 7 days the lunar orbit moves southward to face South declination of ∠-18.900° in the next southern standstill on 25 January 2017 at 11:59 in ♑ Capricorn.
Syzygy in 10 days
After 10 days on 28 January 2017 at 00:07 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
