Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 5 January 2091 at 15:50.

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 ♍ Virgo

Moon is passing about ∠10° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1961"

Lunar disc appears visually 0.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1961" and ∠1951".

Wolf Moon before 3 days

Next Full Moon is the Snow Moon of February 2091 after 25 days on 4 February 2091 at 04:46.

Upcoming main Moon phases

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 1125 / 2078

The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1125 of Meeus index or 2078 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.63 days

Length of current 1125 lunation is 29 days, 15 hours and 2 minutes. It is 2 hours and 5 minutes shorter than next lunation 1126 length.

Lunation length longer than mean

Length of current synodic month is 2 hours and 18 minutes longer than the mean length of synodic month, but it is still 4 hours and 45 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠65.8°

This New Moon true anomaly is ∠65.8°. At beginning of next synodic month true anomaly will be ∠102°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon in perigee

Moon is reaching point of perigee on this date at 22:29, this is 12 days after last apogee on 28 December 2090 at 17:47 in ♓ Pisces. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 16 days ahead, until it will get to the point of next apogee on 25 January 2091 at 14:57 in ♈ Aries.

Previous apogeeNext apogee

Distance to Moon 368 696 km

This perigee Moon is 368 696 km (229 097 mi) away from Earth. It is 6 188 km closer than the mean perigee distance, but it is still 1 660 km farther than the closest perigee of 21st century.

Moon in ascending node

Moon is in ascending node in ♍ Virgo at 17:43 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 23 January 2091 at 02:24 in ♓ Pisces.

Previous nodeNext node

New draconic month

At 17:43 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon after northern standstill

4 days after previous North standstill on 4 January 2091 at 20:03 in ♊ Gemini, when Moon has reached northern declination of ∠18.625°. Next 8 days the lunar orbit moves southward to face South declination of ∠-18.589° in the next southern standstill on 17 January 2091 at 18:01 in ♐ Sagittarius.

Previous standstillNext standstill

Syzygy in 10 days

After 10 days on 19 January 2091 at 16:31 in ♑ Capricorn, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
