Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 24 January 2018 at 22:20.

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 ∠1962"

Lunar disc appears visually 0.7% wider than solar disc. Moon and Sun apparent angular diameters are ∠1962" and ∠1948".

Wolf Moon after 4 days

Next Full Moon is the Wolf Moon of January 2018 after 4 days on 31 January 2018 at 13:27.

Upcoming main Moon phases

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 223 / 1176

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 223 of Meeus index or 1176 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.78 days

Length of current 223 lunation is 29 days, 18 hours and 48 minutes. This is the year's longest synodic month of 2018. It is 2 hours and 42 minutes longer than next lunation 224 length.

Lunation length longer than mean

Length of current synodic month is 7 hours and 3 minutes longer than the mean length of synodic month, but it is still 59 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠198.1°

This lunation true anomaly is ∠198.1°. At the beginning of next synodic month true anomaly will be ∠227.1°. 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 perigee

12 days after point of apogee on 15 January 2018 at 02:10 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 2 days, until it get to the point of next perigee on 30 January 2018 at 09:54 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 365 388 km

Moon is 365 388 km (227 042 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 358 995 km (223 069 mi).

Moon before ascending node

8 days after its descending node on 18 January 2018 at 14:28 in ♒ Aquarius, the Moon is following the southern part of its orbit for the next 4 days, until it will cross the ecliptic from South to North in ascending node on 31 January 2018 at 18:46 in ♌ Leo.

Draconic month

23 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the second to the final part of it.

Moon before northern standstill

11 days after previous South standstill on 15 January 2018 at 16:28 in ♑ Capricorn, when Moon has reached southern declination of ∠-20.048°. Next day the lunar orbit moves northward to face North declination of ∠20.027° in the next northern standstill on 29 January 2018 at 11:32 in ♋ Cancer.

Syzygy in 4 days

After 4 days on 31 January 2018 at 13:27 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
