Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 97% and getting smaller. Lunar cycle is 16 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠10° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 10 September 2003 at 16:36.

Harvest Moon before 1 day

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

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1796"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1796" and ∠1907".

Lunation 45 / 998

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 45 of Meeus index or 998 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 43 minutes and it is 2 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit 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 details for

True anomaly ∠301°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠301° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠325.5°.

Moon before apogee

11 days since point of perigee on 31 August 2003 at 18:47 in ♎ Libra the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next apogee on 16 September 2003 at 09:22 in ♉ Taurus.

Distance to Moon 399 174 km

The Moon is 399 174 km (248 035 mi) away from Earth and getting further over the next 3 days until the point apogee when Earth-Moon distance is going to be 404 713 km (251 477 mi).

Moon before ascending node

10 days after descending node on 2 September 2003 at 07:23 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 3 days until the lunar crosses the ecliptic again from South to North in ascending node on 15 September 2003 at 23:28 in ♉ Taurus.

Moon after southern standstill

7 days since the last southern 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 7 days to face maximum declination of ∠26.874° at the point of next northern standstill on 19 September 2003 at 19:56 in ♋ Cancer.

Draconic month

23 days since the beginning of this draconic month in ♉ Taurus the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 13 days

In 13 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.
