First Quarter in Capricorn

First Quarter on . The illuminated surface of the moon is 51% and growing larger. The lunar cycle is 7 days young.

* The exact date and time of this First Quarter phase is on 24 September 2001 at 09:31 UTC.

Moonrise and moonset

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

Moon phase and lunation details

Moon is entering ♑ Capricorn

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

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.

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.

Apparent angular diameter ∠1820"

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

Lunation 21 / 974

The Moon is 7 days young and navigating through the first part of the current synodic month. This is lunation 21 of Meeus index or 974 from Brown series.

Synodic month length 29.37 days

The length of this lunation is 29 days, 8 hours and 56 minutes and it is 2 hours and 21 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 details for

True anomaly ∠13.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠13.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠30.5°.

Moon before apogee

7 days since 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 in descending node

Moon is in descending node in ♑ Capricorn at 10:28 crossing the ecliptic from North to South. Lunar position remains south of if for the upcoming 14 days until Moon's next ascending node later on 8 October 2001 at 22:32 in ♊ Gemini.

Moon before southern standstill

11 days since the last northern 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.

Draconic month

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

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.
