Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 30 November 2001 at 20:49.

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 ♋ Cancer

Moon is leaving the last ∠1° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1945"

Lunar disc appears visually 0.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1947".

Beaver Moon before 3 days

Next Full Moon is the Cold Moon of December 2001 after 25 days on 30 December 2001 at 10:41.

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 23 / 976

The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 23 of Meeus index or 976 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.59 days

Length of current 23 lunation is 29 days, 14 hours and 7 minutes. It is 2 hours and 34 minutes shorter than next lunation 24 length.

Lunation length longer than mean

Length of current synodic month is 1 hour and 23 minutes longer than the mean length of synodic month, but it is still 5 hours and 40 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠53.5°

This New Moon true anomaly is ∠53.5°. At beginning of next synodic month true anomaly will be ∠86.2°. 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 before perigee

10 days after point of apogee on 23 November 2001 at 15:46 in ♓ Pisces. 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 6 December 2001 at 22:48 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 368 496 km

Moon is 368 496 km (228 973 mi) away from Earth on this date. Moon moves closer next 2 days until perigee, when Earth-Moon distance will reach 370 114 km (229 978 mi).

Moon after ascending node

2 days after its ascending node on 2 December 2001 at 05:30 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 15 December 2001 at 04:32 in ♐ Sagittarius.

Draconic month

2 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the beginning to the first part of it.

Moon after northern standstill

1 day after previous North standstill on 3 December 2001 at 06:54 in ♋ Cancer, when Moon has reached northern declination of ∠24.246°. Next 11 days the lunar orbit moves southward to face South declination of ∠-24.250° in the next southern standstill on 16 December 2001 at 07:51 in ♑ Capricorn.

Syzygy in 10 days

After 10 days on 14 December 2001 at 20:48 in ♐ Sagittarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
