Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♈ Aries

Moon is passing about ∠13° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1880"

Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1880" and ∠1951".

Cold Moon after 7 days

Next Full Moon is the Cold Moon of December 2066 after 7 days on 31 December 2066 at 14:41.

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 828 / 1781

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 828 of Meeus index or 1781 from Brown series.

Synodic month length 29.46 days

Length of current 828 lunation is 29 days, 10 hours and 59 minutes. This is the year's shortest synodic month of 2066. It is 19 minutes longer than next lunation 829 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 45 minutes shorter than the mean length of synodic month, but it is still 4 hours and 24 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠346.7°

This New Moon true anomaly is ∠346.7°. At beginning of next synodic month true anomaly will be ∠2.4°. 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

19 days after point of apogee on 5 December 2066 at 07:41 in ♋ Cancer. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 26 December 2066 at 09:01 in ♉ Taurus.

Distance to Moon 381 197 km

Moon is 381 197 km (236 865 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 358 544 km (222 789 mi).

Moon before descending node

7 days after its ascending node on 17 December 2066 at 07:22 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 30 December 2066 at 17:42 in ♊ Gemini.

Draconic month

7 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

7 days after previous South standstill on 16 December 2066 at 13:29 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.934°. Next 5 days the lunar orbit moves northward to face North declination of ∠23.938° in the next northern standstill on 29 December 2066 at 18:32 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 31 December 2066 at 14:41 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
