Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 92% and getting smaller. Lunar cycle is 17 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 ♉ Taurus

Moon is passing first ∠0° of ♉ Taurus tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 18 September 2005 at 02:01.

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2005 after 27 days on 17 October 2005 at 12:14.

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 ∠1899"

Lunar disc appears visually 0.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1899" and ∠1911".

Lunation 70 / 1023

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 70 of Meeus index or 1023 from Brown series.

Synodic month length 29.65 days

The length of this lunation is 29 days, 15 hours and 42 minutes and it is 45 minutes longer than the upcoming lunation's length. This is the year's longest synodic month of 2005. 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 58 minutes longer than the mean synodic month length. It is 4 hours and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠205.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠205.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠236.1°.

Moon after perigee

3 days since point of perigee on 16 September 2005 at 13:58 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 8 days until the Moon reaches the point of next apogee on 28 September 2005 at 15:20 in ♌ Leo.

Distance to Moon 377 448 km

The Moon is 377 448 km (234 535 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 405 307 km (251 846 mi).

Moon after ascending node

1 day after ascending node on 19 September 2005 at 08:09 in ♈ Aries the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 3 October 2005 at 16:51 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 12 September 2005 at 10:54 in ♑ Capricorn when the Moon has reached South declination of ∠-28.556° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠28.594° at the point of next northern standstill on 25 September 2005 at 06:42 in ♋ Cancer.

Draconic month

1 day since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 12 days

In 12 days on 3 October 2005 at 10:28 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.
