Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 68% 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 ∠22° of ♈ Aries tropical zodiac sector.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 31 July 2015 at 10:43.

Buck Moon before 5 days

Next Full Moon is the Sturgeon Moon of August 2015 after 24 days on 29 August 2015 at 18:35.

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 ∠1964"

Lunar disc appears visually 3.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1892".

Lunation 192 / 1145

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 192 of Meeus index or 1145 from Brown series.

Synodic month length 29.56 days

The length of this lunation is 29 days, 13 hours and 29 minutes and it is 2 hours and 19 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 45 minutes longer than the mean synodic month length. It is 6 hours and 18 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠112.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠112.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠144.1°.

Moon after perigee

3 days since point of perigee on 2 August 2015 at 10:11 in ♓ Pisces the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 12 days until the Moon reaches the point of next apogee on 18 August 2015 at 02:33 in ♎ Libra.

Distance to Moon 364 924 km

The Moon is 364 924 km (226 753 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 405 852 km (252 185 mi).

Moon after descending node

1 day after descending node on 4 August 2015 at 02:53 in ♈ Aries the Moon is positioned south of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from South to North in ascending node on 17 August 2015 at 23:05 in ♍ Virgo.

Moon before northern standstill

7 days since the last southern standstill on 28 July 2015 at 17:34 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.344° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.288° at the point of next northern standstill on 10 August 2015 at 11:11 in ♊ Gemini.

Draconic month

14 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 9 days

In 9 days on 14 August 2015 at 14:54 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.
