Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 67% and getting smaller. The lunar cycle is 20 days old.

Moonrise and moonset

The 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 phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠13° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 21 July 2005 at 11:00.

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2005 after 24 days on 19 August 2005 at 17:53.

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.

Apparent angular diameter ∠1917"

Lunar disc appears visually 1.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1917" and ∠1889".

Lunation 68 / 1021

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 68 of Meeus index or 1021 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 2 minutes and it is 39 minutes shorter 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 18 minutes longer than the mean synodic month length. It is 4 hours and 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠158.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠158.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠181.9°.

Moon after perigee

4 days since point of perigee on 21 July 2005 at 19:44 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 4 August 2005 at 21:49 in ♌ Leo.

Distance to Moon 373 855 km

The Moon is 373 855 km (232 303 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 406 631 km (252 669 mi).

Moon in ascending node

Moon is in ascending node in ♈ Aries at 17:58 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 10 August 2005 at 07:53 in ♎ Libra.

Moon before northern standstill

6 days since the last southern standstill on 19 July 2005 at 17:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.265° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.311° at the point of next northern standstill on 1 August 2005 at 18:06 in ♊ Gemini.

New draconic month

At 17:58 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 9 days

In 9 days on 5 August 2005 at 03:05 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.
