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 ∠18° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1863"

Lunar disc appears visually 2.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1863" and ∠1904".

Harvest Moon after 7 days

Next Full Moon is the Harvest Moon of September 2019 after 7 days on 14 September 2019 at 04:33.

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 243 / 1196

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 243 of Meeus index or 1196 from Brown series.

Synodic month length 29.33 days

The length of the lunation is 29 days, 7 hours and 49 minutes. It is 1 hour and 23 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 55 minutes shorter than the mean synodic month length. It is 1 hour and 14 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠356.3°

At the beginning of the lunation cycle the true anomaly is ∠356.3°. At the beginning of next synodic month the true anomaly is going to be ∠11.4°.

Moon after perigee

6 days after point of perigee on 30 August 2019 at 15:57 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 7 days, until the Moon reaches the point of next apogee on 13 September 2019 at 13:32 in ♓ Pisces.

Distance to Moon 384 781 km

The Moon is 384 781 km (239 092 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 378 km (252 512 mi).

Moon before descending node

10 days after ascending node on 27 August 2019 at 01:50 in ♋ Cancer. The Moon is located north of the ecliptic over the following 2 days, until the lunar orbit crosses from North to South in descending node on 8 September 2019 at 17:35 in ♑ Capricorn.

Draconic month

10 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

10 days since the previous standstill on 26 August 2019 at 17:53 in ♋ Cancer when the Moon has reached North declination of ∠22.473°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-22.539° at the point of next southern standstill on 8 September 2019 at 09:39 in ♑ Capricorn.

Syzygy in 7 days

In 7 days on 14 September 2019 at 04:33 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.
