Moon phase and lunation details

7 days after First Quarter

Previous main lunar phase is the First Quarter before 7 days on 22 December 2039 at 10:01.

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 leaving the last ∠3° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.

Apparent angular diameter ∠1768"

Lunar disc appears visually 9.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1951".

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2039 after 1 day on 30 December 2039 at 12:37.

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 494 / 1447

The Moon is 14 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 494 of Meeus index or 1447 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

Length of current 494 lunation is 29 days, 10 hours and 53 minutes. It is 6 minutes shorter than next lunation 495 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 51 minutes shorter than the mean length of synodic month, but it is still 4 hours and 18 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠356.9°

This New Moon true anomaly is ∠356.9°. At beginning of next synodic month true anomaly will be ∠12.4°. 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 in apogee

Moon is reaching point of apogee on this date at 16:34, this is 13 days after last perigee on 15 December 2039 at 20:51 in ♐ Sagittarius. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 14 days ahead, until it will get to the point of next perigee on 13 January 2040 at 10:03 in ♑ Capricorn.

Previous perigeeNext perigee

Distance to Moon 406 355 km

This apogee Moon is 406 355 km (252 497 mi) away from Earth. It is 947 km farther than the mean apogee distance, but it is still 354 km closer than the farthest apogee of 21st century.

Moon after ascending node

1 day after its ascending node on 28 December 2039 at 08:24 in ♊ Gemini, the Moon is following the northern part of its orbit for the next 12 days, until it will cross the ecliptic from North to South in descending node on 11 January 2040 at 10:06 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

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

Moon before northern standstill

12 days after previous South standstill on 16 December 2039 at 19:27 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.464°. Next day the lunar orbit moves northward to face North declination of ∠25.448° in the next northern standstill on 30 December 2039 at 16:29 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 1 day

After 1 day on 30 December 2039 at 12:37 in ♋ Cancer, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
