Waning Gibbous in Taurus

Waning Gibbous on . Illuminated surface of the Moon is 84% 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 in ♉ Taurus

Moon is passing about ∠25° of ♉ Taurus tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 28 September 2015 at 02:50.

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2015 after 26 days on 27 October 2015 at 12:05.

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 ∠1935"

Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1935" and ∠1917".

Lunation 194 / 1147

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 194 of Meeus index or 1147 from Brown series.

Synodic month length 29.73 days

The length of this lunation is 29 days, 17 hours and 24 minutes and it is 17 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 4 hours and 40 minutes longer than the mean synodic month length. It is 2 hours and 23 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠169.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠169.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠192.9°.

Moon after perigee

3 days since point of perigee on 28 September 2015 at 01:46 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next apogee on 11 October 2015 at 13:17 in ♍ Virgo.

Distance to Moon 370 352 km

The Moon is 370 352 km (230 126 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 389 km (252 518 mi).

Moon after descending node

3 days after descending node on 27 September 2015 at 21:04 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 11 October 2015 at 10:54 in ♎ Libra.

Moon before northern standstill

9 days since the last southern standstill on 21 September 2015 at 12:02 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.134° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠18.140° at the point of next northern standstill on 3 October 2015 at 23:55 in ♊ Gemini.

Draconic month

17 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 11 days

In 11 days on 13 October 2015 at 00:06 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.
