Moon phase and lunation details

2 days after Last Quarter

Previous main lunar phase is the Last Quarter before 2 days on 10 September 2001 at 19:00.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♋ Cancer

Moon is leaving the last ∠4° of ♋ Cancer tropical zodiac sector and will enter ♌ Leo later.

Apparent angular diameter ∠1954"

Lunar disc appears visually 2.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1954" and ∠1907".

Hunter Moon after 19 days

Next Full Moon is the Hunter Moon of October 2001 after 19 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 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 20 of Meeus index or 973 from Brown series.

PreviousCurrent lunationNext

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 before apogee

11 days after point of apogee on 1 September 2001 at 23:26 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 3 days, until the Moon reaches the point of next perigee on 16 September 2001 at 15:50 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 366 886 km

The Moon is 366 886 km (227 972 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 358 128 km (222 530 mi).

Moon after ascending node

1 day after ascending node on 11 September 2001 at 21:36 in ♊ Gemini. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 24 September 2001 at 10:28 in ♑ Capricorn.

Draconic month

1 day since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the beginning to the first part of the cycle.

Moon after northern standstill

1 day 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 11 days 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 3 days

In 3 days on 17 September 2001 at 10:27 in ♍ Virgo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
