Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 31 January 2018 at 13:27.

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 ♌ Leo

Moon is leaving the last ∠4° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Apparent angular diameter ∠1942"

Lunar disc appears visually 0.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1942" and ∠1947".

Wolf Moon before 1 day

Next Full Moon is the Worm Moon of March 2018 after 28 days on 2 March 2018 at 00:51.

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 16 days old. Earth's natural satellite is moving from the middle to the last 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 after perigee

2 days after point of perigee on 30 January 2018 at 09:54 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 10 days, until it get to the point of next apogee on 11 February 2018 at 14:16 in ♐ Sagittarius.

Previous perigeeNext apogee

Distance to Moon 369 084 km

Moon is 369 084 km (229 338 mi) away from Earth on this date. Moon moves farther next 10 days until apogee, when Earth-Moon distance will reach 405 701 km (252 091 mi).

Moon after ascending node

1 day after its ascending node on 31 January 2018 at 18:46 in ♌ Leo, the Moon is following the northern part of its orbit for the next 13 days, until it will cross the ecliptic from North to South in descending node on 14 February 2018 at 21:11 in ♒ Aquarius.

Draconic month

1 day after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.

Moon after northern standstill

3 days after previous North standstill on 29 January 2018 at 11:32 in ♋ Cancer, when Moon has reached northern declination of ∠20.027°. Next 10 days the lunar orbit moves southward to face South declination of ∠-20.026° in the next southern standstill on 11 February 2018 at 23:21 in ♑ Capricorn.

Syzygy in 14 days

After 14 days on 15 February 2018 at 21:05 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
