Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 58% and getting smaller. Lunar cycle is 21 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 ∠7° of ♈ Aries tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 2 July 2004 at 11:09.

Buck Moon before 6 days

Next Full Moon is the Buck Moon of July 2004 after 23 days on 31 July 2004 at 18:05.

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 ∠1853"

Lunar disc appears visually 1.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1853" and ∠1887".

Lunation 55 / 1008

The Moon is 21 days old and navigating from the middle to the last part of the current synodic month. This is lunation 55 of Meeus index or 1008 from Brown series.

Synodic month length 29.62 days

The length of this lunation is 29 days, 14 hours and 57 minutes and it is 57 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 longer than mean

The length of the current synodic month is 2 hours and 13 minutes longer than the mean synodic month length. It is 4 hours and 50 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠181.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠181.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠205.1°.

Moon before apogee

6 days since point of perigee on 1 July 2004 at 23:00 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 14 July 2004 at 21:08 in ♊ Gemini.

Distance to Moon 386 761 km

The Moon is 386 761 km (240 322 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 406 192 km (252 396 mi).

Moon before ascending node

10 days after descending node on 28 June 2004 at 08:37 in ♏ Scorpio the Moon is positioned south of the ecliptic over the following 2 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 July 2004 at 00:59 in ♉ Taurus.

Moon after southern standstill

6 days since the last southern standstill on 2 July 2004 at 03:43 in ♑ Capricorn when the Moon has reached South declination of ∠-27.538° the lunar orbit is extending northward over the next 7 days to face maximum declination of ∠27.543° at the point of next northern standstill on 15 July 2004 at 20:46 in ♋ Cancer.

Draconic month

24 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 8 days

In 8 days on 17 July 2004 at 11:24 in ♋ Cancer 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.
