Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon is entering ♐ Sagittarius

Moon is passing first ∠4° of ♐ Sagittarius tropical zodiac sector.

Next Full Moon is the Snow Moon of February 2027 after 20 days on 20 February 2027 at 23:23.

Upcoming main Moon phases

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 334 / 1287

The Moon is 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 334 of Meeus index or 1287 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.81 days

Length of current 334 lunation is 29 days, 19 hours and 32 minutes. This is the year's longest synodic month of 2027. It is 1 hour and 59 minutes longer than next lunation 335 length.

Lunation length longer than mean

Length of current synodic month is 6 hours and 48 minutes longer than the mean length of synodic month, but it is still 15 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠184.3°

This lunation true anomaly is ∠184.3°. At the beginning of next synodic month true anomaly will be ∠210.4°. 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

9 days after point of perigee on 21 January 2027 at 21:49 in ♋ Cancer. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 3 days, until it get to the point of next apogee on 3 February 2027 at 13:31 in ♑ Capricorn.

Previous perigeeNext apogee

Distance to Moon 399 893 km

Moon is 399 893 km (248 482 mi) away from Earth on this date. Moon moves farther next 3 days until apogee, when Earth-Moon distance will reach 406 189 km (252 394 mi).

Moon before ascending node

7 days after its descending node on 23 January 2027 at 17:26 in ♌ Leo, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 6 February 2027 at 21:44 in ♒ Aquarius.

Moon before southern standstill

11 days after previous North standstill on 19 January 2027 at 23:16 in ♊ Gemini, when Moon has reached northern declination of ∠27.682°. Next day the lunar orbit moves southward to face South declination of ∠-27.706° in the next southern standstill on 2 February 2027 at 02:38 in ♐ Sagittarius.

Syzygy in 6 days

After 6 days on 6 February 2027 at 15:56 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
