Moon phase and lunation details

6 days after Last Quarter

Previous main lunar phase is the Last Quarter before 6 days on 29 August 2040 at 11:16.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♌ Leo

Moon is passing about ∠19° of ♌ Leo tropical zodiac sector.

Harvest Moon after 16 days

Next Full Moon is the Harvest Moon of September 2040 after 16 days on 20 September 2040 at 17:43.

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 502 / 1455

The Moon is 27 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 502 of Meeus index or 1455 from Brown series.

Synodic month length 29.62 days

The length of the lunation is 29 days, 14 hours and 47 minutes. It is 35 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 2 hours and 3 minutes longer than the mean synodic month length. It is 5 hours shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠199°

At the beginning of the lunation cycle the true anomaly is ∠199°. At the beginning of next synodic month the true anomaly is going to be ∠226.5°.

Moon after apogee

2 days after point of apogee on 2 September 2040 at 10:15 in ♋ Cancer. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 13 days, until the Moon reaches the point of next perigee on 18 September 2040 at 06:43 in ♒ Aquarius.

Previous apogeeNext perigee

Distance to Moon 403 985 km

The Moon is 403 985 km (251 025 mi) away from Earth and getting closer over the next 13 days until the point perigee when Earth-Moon distance is going to be 363 882 km (226 106 mi).

Moon after ascending node

6 days after ascending node on 28 August 2040 at 19:18 in ♉ Taurus. The Moon is located north of the ecliptic over the following 7 days, until the lunar orbit crosses from North to South in descending node on 12 September 2040 at 06:11 in ♏ Scorpio.

Draconic month

6 days since the beginning of current draconic month in ♉ Taurus, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

3 days since the previous standstill on 1 September 2040 at 03:14 in ♋ Cancer when the Moon has reached North declination of ∠26.397°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-26.529° at the point of next southern standstill on 15 September 2040 at 06:36 in ♑ Capricorn.

Syzygy in 2 days

In 2 days on 6 September 2040 at 15:13 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
