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 ♐ Sagittarius

Moon is passing about ∠23° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1859"

Lunar disc appears visually 2.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1859" and ∠1906".

Harvest Moon after 7 days

Next Full Moon is the Harvest Moon of September 2081 after 7 days on 18 September 2081 at 03:45.

Upcoming main Moon phases

Neap tide

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 1010 / 1963

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 1010 of Meeus index or 1963 from Brown series.

Synodic month length 29.35 days

The length of the lunation is 29 days, 8 hours and 22 minutes. It is 1 hour and 19 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 4 hours and 22 minutes shorter than the mean synodic month length. It is 1 hour and 47 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠357.1°

At the beginning of the lunation cycle the true anomaly is ∠357.1°. At the beginning of next synodic month the true anomaly is going to be ∠12.5°.

Moon before perigee

6 days after point of perigee on 3 September 2081 at 13:09 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 6 days, until the Moon reaches the point of next apogee on 17 September 2081 at 08:20 in ♓ Pisces.

Distance to Moon 385 558 km

The Moon is 385 558 km (239 575 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 234 km (252 422 mi).

Moon before ascending node

6 days after descending node on 3 September 2081 at 14:55 in ♍ Virgo. The Moon is located south of the ecliptic over the following 6 days, until the lunar orbit crosses from South to North in ascending node on 17 September 2081 at 06:18 in ♓ Pisces.

Draconic month

20 days since the beginning of current draconic month in ♓ Pisces, the Moon is navigating from the second to the final part of the cycle.

Moon at southern standstill

At 20:08 the Moon is meeting its standstill point to reach South declination of ∠-28.547°. Over the next 15 days the lunar orbit is going to extend northward to face maximum declination of ∠28.512° at the point of next standstill in ♊ Gemini on 25 September 2081 at 14:31.

Syzygy in 7 days

In 7 days on 18 September 2081 at 03:45 in ♓ Pisces the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
