Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 11 September 2079 at 05:36.

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.

Harvest Moon before 6 days

Next Full Moon is the Hunter Moon of October 2079 after 23 days on 10 October 2079 at 17:23.

Upcoming main Moon phases

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 985 / 1938

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 985 of Meeus index or 1938 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.46 days

Length of current 985 lunation is 29 days, 11 hours and 3 minutes. It is 3 hours and 11 minutes shorter than next lunation 986 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 41 minutes shorter than the mean length of synodic month, but it is still 4 hours and 28 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠50.5°

This New Moon true anomaly is ∠50.5°. At beginning of next synodic month true anomaly will be ∠80.4°. 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

13 days after point of apogee on 4 September 2079 at 08:27 in ♐ Sagittarius. 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 18 September 2079 at 08:26 in ♊ Gemini.

Distance to Moon 363 662 km

Moon is 363 662 km (225 969 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 369 896 km (229 843 mi).

Moon after ascending node

3 days after its ascending node on 13 September 2079 at 17:20 in ♈ Aries, the Moon is following the northern part of its orbit for the next 9 days, until it will cross the ecliptic from North to South in descending node on 26 September 2079 at 16:35 in ♎ Libra.

Moon before northern standstill

12 days after previous South standstill on 5 September 2079 at 06:20 in ♑ Capricorn, when Moon has reached southern declination of ∠-28.246°. Next day the lunar orbit moves northward to face North declination of ∠28.319° in the next northern standstill on 18 September 2079 at 20:00 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 7 days

After 7 days on 25 September 2079 at 04:06 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
