Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 16 September 2016 at 19:05.

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.

Moon is entering ♊ Gemini

Moon is passing first ∠4° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1967"

Lunar disc appears visually 2.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1912".

Harvest Moon before 4 days

Next Full Moon is the Hunter Moon of October 2016 after 24 days on 16 October 2016 at 04:23.

Upcoming main Moon phases

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.

Lunation 206 / 1159

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 206 of Meeus index or 1159 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.63 days

The length of the lunation is 29 days, 15 hours and 8 minutes. It is 2 hours and 19 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the 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 position on

True anomaly ∠112.8°

At the beginning of the lunation cycle the true anomaly is ∠112.8°. At the beginning of next synodic month the true anomaly is going to be ∠144.6°.

Moon after perigee

2 days after point of perigee on 18 September 2016 at 17:00 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 12 days, until the Moon reaches the point of next apogee on 4 October 2016 at 11:02 in ♏ Scorpio.

Previous perigeeNext apogee

Distance to Moon 364 398 km

The Moon is 364 398 km (226 426 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 406 100 km (252 339 mi).

Moon after descending node

5 days after descending node on 15 September 2016 at 23:55 in ♓ Pisces. The Moon is located south of the ecliptic over the following 7 days, until the lunar orbit crosses from South to North in ascending node on 28 September 2016 at 22:06 in ♍ Virgo.

Draconic month

19 days since the beginning of current draconic month in ♍ Virgo, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

10 days since the previous 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 2 days to face maximum declination of ∠18.475° at the point of next northern standstill on 23 September 2016 at 16:44 in ♊ Gemini.

Syzygy in 9 days

In 9 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.
