Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon is entering ♑ Capricorn

Moon is passing first ∠3° of ♑ Capricorn tropical zodiac sector.

Apparent angular diameter ∠1820"

Lunar disc appears visually 5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1820" and ∠1913".

Hunter Moon after 8 days

Next Full Moon is the Hunter Moon of October 2001 after 8 days on 2 October 2001 at 13:49.

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.

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 21 of Meeus index or 974 from Brown series.

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 56 minutes. It is 2 hours and 21 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 3 hours and 48 minutes shorter than the mean synodic month length. It is 2 hours and 21 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠13.2°

At the beginning of the lunation cycle the true anomaly is ∠13.2°. At the beginning of next synodic month the true anomaly is going to be ∠30.5°.

Moon before perigee

7 days after point of perigee on 16 September 2001 at 15:50 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 4 days, until the Moon reaches the point of next apogee on 29 September 2001 at 05:33 in ♒ Aquarius.

Distance to Moon 393 860 km

The Moon is 393 860 km (244 733 mi) away from Earth and getting further over the next 4 days until the point apogee when Earth-Moon distance is going to be 405 791 km (252 147 mi).

Moon before southern standstill

11 days since the previous standstill on 12 September 2001 at 12:19 in ♋ Cancer when the Moon has reached North declination of ∠23.677°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-23.780° at the point of next southern standstill on 25 September 2001 at 05:14 in ♑ Capricorn.

Syzygy in 8 days

In 8 days on 2 October 2001 at 13:49 in ♈ Aries 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.
