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 ∠17° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1915"

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1907".

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2002 after 8 days on 21 September 2002 at 13:59.

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 33 / 986

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 33 of Meeus index or 986 from Brown series.

Synodic month length 29.34 days

The length of the lunation is 29 days, 8 hours and 7 minutes. It is 1 hour and 10 minutes shorter 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 shorter than mean

The length of the current synodic month is 4 hours and 37 minutes shorter than the mean synodic month length. It is 1 hour and 32 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠343.1°

At the beginning of the lunation cycle the true anomaly is ∠343.1°. At the beginning of next synodic month the true anomaly is going to be ∠358.6°.

Moon after perigee

5 days after point of perigee on 8 September 2002 at 03:14 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 9 days, until the Moon reaches the point of next apogee on 23 September 2002 at 03:26 in ♈ Aries.

Distance to Moon 374 295 km

The Moon is 374 295 km (232 576 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 351 km (252 495 mi).

Moon in descending node

Moon is in descending node in ♐ Sagittarius at 03:39 crossing the ecliptic from North to South to meet ascending node 14 days later on 27 September 2002 at 16:06 in ♊ Gemini.

Draconic month

12 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the middle to the last part of the cycle.

Moon before southern standstill

10 days since the previous standstill on 2 September 2002 at 16:03 in ♋ Cancer when the Moon has reached North declination of ∠25.282°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-25.377° at the point of next southern standstill on 15 September 2002 at 05:34 in ♑ Capricorn.

Syzygy in 8 days

In 8 days on 21 September 2002 at 13:59 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.
