Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 10 September 2003 at 16:36.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♊ Gemini

Moon is passing about ∠10° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1771"

Lunar disc appears visually 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1909".

Harvest Moon before 6 days

Next Full Moon is the Hunter Moon of October 2003 after 22 days on 10 October 2003 at 07:27.

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 45 / 998

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 45 of Meeus index or 998 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.4 days

The length of the lunation is 29 days, 9 hours and 43 minutes. It is 2 minutes longer 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 3 hours and 1 minute shorter than the mean synodic month length. It is 3 hours and 8 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠301°

At the beginning of the lunation cycle the true anomaly is ∠301°. At the beginning of next synodic month the true anomaly is going to be ∠325.5°.

Moon after apogee

1 day after point of apogee on 16 September 2003 at 09:22 in ♉ Taurus. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 28 September 2003 at 05:59 in ♏ Scorpio.

Previous apogeeNext perigee

Distance to Moon 404 617 km

The Moon is 404 617 km (251 417 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 362 837 km (225 456 mi).

Moon after ascending node

1 day after ascending node on 15 September 2003 at 23:28 in ♉ Taurus. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 29 September 2003 at 10:34 in ♏ Scorpio.

Draconic month

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

Moon before northern standstill

12 days since the previous standstill on 5 September 2003 at 11:54 in ♑ Capricorn when the Moon has reached South declination of ∠-26.746°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.874° at the point of next northern standstill on 19 September 2003 at 19:56 in ♋ Cancer.

Syzygy in 8 days

In 8 days on 26 September 2003 at 03:09 in ♎ Libra 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.
