Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 96% and getting smaller. The lunar cycle is 16 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 ∠19° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 16 September 2016 at 19:05.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2016 after 27 days on 16 October 2016 at 04:23.

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 2.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1964" and ∠1910".

Lunation 206 / 1159

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 206 of Meeus index or 1159 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 8 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 2 hours and 24 minutes longer than the mean synodic month length. It is 4 hours and 39 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 ∠144.6°.

Moon at perigee

Moon is at perigee at 17:00 about 11 days since last apogee on 6 September 2016 at 18:44 in ♏ Scorpio the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 15 days until point of next apogee on 4 October 2016 at 11:02 in ♏ Scorpio.

Distance to Moon 361 894 km

This perigee Moon is 361 894 km (224 871 mi) away from Earth. It is 614 km closer than the mean perigee distance, but it is still 8 462 km further than the closest perigee of 21st century.

Moon after descending node

2 days after descending node on 15 September 2016 at 23:55 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 28 September 2016 at 22:06 in ♍ Virgo.

Moon before northern standstill

7 days since the last southern standstill on 10 September 2016 at 22:05 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.451° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠18.475° at the point of next northern standstill on 23 September 2016 at 16:44 in ♊ Gemini.

Draconic month

16 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 12 days

In 12 days on 1 October 2016 at 00:12 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.
