Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 12 December 2078 at 07:52.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♊ Gemini

Moon is passing about ∠5° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1950".

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2078 after 1 day on 18 December 2078 at 23:34.

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 976 / 1929

The Moon is 13 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 976 of Meeus index or 1929 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.78 days

Length of current 976 lunation is 29 days, 18 hours and 42 minutes. It is 1 hour and 57 minutes longer than next lunation 977 length.

Lunation length longer than mean

Length of current synodic month is 5 hours and 58 minutes longer than the mean length of synodic month, but it is still 1 hour and 5 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠196.6°

This lunation true anomaly is ∠196.6°. At the beginning of next synodic month true anomaly will be ∠225.6°. 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 in perigee

Moon is reaching point of perigee on this date at 21:10, this is 15 days after last apogee on 2 December 2078 at 15:34 in ♏ Scorpio. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the point of next apogee on 30 December 2078 at 02:17 in ♏ Scorpio.

Previous apogeeNext apogee

Distance to Moon 358 828 km

This perigee Moon is 358 828 km (222 965 mi) away from Earth. It is 3 680 km closer than the mean perigee distance, but it is still 11 528 km farther than the closest perigee of 21st century.

Moon after ascending node

1 day after its ascending node on 15 December 2078 at 19:09 in ♉ Taurus, the Moon is following the northern part of its orbit for the next 11 days, until it will cross the ecliptic from North to South in descending node on 28 December 2078 at 21:50 in ♏ Scorpio.

Previous nodeNext node

Draconic month

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

Moon before northern standstill

10 days after previous South standstill on 6 December 2078 at 12:06 in ♑ Capricorn, when Moon has reached southern declination of ∠-27.555°. Next 2 days the lunar orbit moves northward to face North declination of ∠27.536° in the next northern standstill on 19 December 2078 at 14:06 in ♊ Gemini.

Syzygy in 1 day

After 1 day on 18 December 2078 at 23:34 in ♊ Gemini, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
