Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 87% and getting smaller. Lunar cycle is 18 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 is entering ♈ Aries

Moon is passing first ∠2° of ♈ Aries tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 9 August 2006 at 10:54.

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2006 after 26 days on 7 September 2006 at 18:42.

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 ∠1972"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1894".

Lunation 81 / 1034

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 81 of Meeus index or 1034 from Brown series.

Synodic month length 29.61 days

The length of this lunation is 29 days, 14 hours and 39 minutes and it is 1 hour and 56 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 longer than mean

The length of the current synodic month is 1 hour and 55 minutes longer than the mean synodic month length. It is 5 hours and 8 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠131.2°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠131.2° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠158.8°.

Moon after perigee

1 day since point of perigee on 10 August 2006 at 18:27 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 26 August 2006 at 01:23 in ♍ Virgo.

Distance to Moon 363 552 km

The Moon is 363 552 km (225 901 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 271 km (252 445 mi).

Moon in ascending node

Moon is in ascending node in ♓ Pisces at 01:31 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 25 August 2006 at 21:34 in ♍ Virgo.

Moon before northern standstill

6 days since the last southern standstill on 6 August 2006 at 04:11 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.594° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.645° at the point of next northern standstill on 18 August 2006 at 19:43 in ♊ Gemini.

New draconic month

At 01:31 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 11 days

In 11 days on 23 August 2006 at 19:10 in ♌ Leo 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.
