Moon phase and lunation details
1 day after Full Moon
Previous main lunar phase is the Full Moon before 1 day on 3 December 2017 at 15:47.
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 in ♊ Gemini
Moon is passing about ∠24° of ♊ Gemini tropical zodiac sector.
Apparent angular diameter ∠1972"
Lunar disc appears visually 1.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1947".
Cold Moon before 1 day
Next Full Moon is the Wolf Moon of January 2018 after 28 days on 2 January 2018 at 02:24.
Upcoming main Moon phases
- Last Quarter in Virgo ♍ on 10 December 2017 at 07:51
- New Moon in Sagittarius ♐ on 18 December 2017 at 06:31
- First Quarter in Aries ♈ on 26 December 2017 at 09:20

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 221 / 1174
The Moon is 15 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 221 of Meeus index or 1174 from Brown series.
Synodic month length 29.78 days
The length of the lunation is 29 days, 18 hours and 48 minutes. It is 59 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 longer than mean
The length of the current synodic month is 6 hours and 4 minutes longer than the mean synodic month length. It is 59 minutes shorter compared to 21st century's longest synodic month length.
Lunar orbit position on
True anomaly ∠147°
At the beginning of the lunation cycle the true anomaly is ∠147°. At the beginning of next synodic month the true anomaly is going to be ∠173.3°.
Moon at perigee
Moon is at perigee at 08:42. It is 12 days after previous apogee on 21 November 2017 at 18:52 in ♐ Sagittarius. Lunar orbit is going to widen while the Moon is moving away from the Earth over the next 14 days, until point of next apogee on 19 December 2017 at 01:27 in ♑ Capricorn.
Distance to Moon 357 496 km
This perigee Moon is 357 496 km (222 138 mi) away from Earth. It is 5 012 km closer than the mean perigee distance, but it is still 12 860 km further than the closest perigee of 21st century.
Moon before ascending node
9 days after descending node on 25 November 2017 at 08:22 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 8 December 2017 at 00:39 in ♌ Leo.
Draconic month
23 days since the beginning of current draconic month in ♌ Leo, 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 22 November 2017 at 02:06 in ♑ Capricorn when the Moon has reached South declination of ∠-19.959°, the lunar orbit is extending northward over the next day to face maximum declination of ∠20.015° at the point of next northern standstill on 5 December 2017 at 11:43 in ♋ Cancer.
Syzygy in 13 days
In 13 days on 18 December 2017 at 06:31 in ♐ Sagittarius the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
