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 ♏ Scorpio

Moon is leaving the last ∠2° of ♏ Scorpio tropical zodiac sector and will enter ♐ Sagittarius later.

Apparent angular diameter ∠1874"

Lunar disc appears visually 1.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1874" and ∠1899".

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2001 after 8 days on 2 September 2001 at 21:43.

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 20 / 973

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 20 of Meeus index or 973 from Brown series.

Synodic month length 29.31 days

The length of the lunation is 29 days, 7 hours and 32 minutes. It is 1 hour and 24 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 5 hours and 12 minutes shorter than the mean synodic month length. It is 57 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠358.1°

At the beginning of the lunation cycle the true anomaly is ∠358.1°. At the beginning of next synodic month the true anomaly is going to be ∠13.2°.

Moon after perigee

6 days after point of perigee on 19 August 2001 at 05:43 in ♌ Leo. 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 1 September 2001 at 23:26 in ♒ Aquarius.

Distance to Moon 382 502 km

The Moon is 382 502 km (237 676 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 406 332 km (252 483 mi).

Moon before descending node

9 days after ascending node on 15 August 2001 at 17:05 in ♊ Gemini. 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 28 August 2001 at 09:09 in ♑ Capricorn.

Moon before southern standstill

9 days since the previous standstill on 16 August 2001 at 03:52 in ♋ Cancer when the Moon has reached North declination of ∠23.488°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-23.546° at the point of next southern standstill on 28 August 2001 at 23:14 in ♑ Capricorn.

Syzygy in 8 days

In 8 days on 2 September 2001 at 21:43 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.
