Moon phase and lunation details

4 days after New Moon

Previous main lunar phase is the New Moon before 4 days on 13 September 2015 at 06:41.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

Moon in ♏ Scorpio

Moon is passing about ∠10° of ♏ Scorpio tropical zodiac sector.

Apparent angular diameter ∠1788"

Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1788" and ∠1909".

Harvest Moon after 10 days

Next Full Moon is the Harvest Moon of September 2015 after 10 days on 28 September 2015 at 02:50.

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 194 / 1147

The Moon is 4 days young. Earth's natural satellite is moving from the beginning to the first part of current synodic month. This is lunation 194 of Meeus index or 1147 from Brown series.

Synodic month length 29.73 days

The length of the lunation is 29 days, 17 hours and 24 minutes. It is 17 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 position on

True anomaly ∠169.3°

At the beginning of the lunation cycle the true anomaly is ∠169.3°. At the beginning of next synodic month the true anomaly is going to be ∠192.9°.

Moon after apogee

3 days after point of apogee on 14 September 2015 at 11:28 in ♎ Libra. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 10 days, until the Moon reaches the point of next perigee on 28 September 2015 at 01:46 in ♈ Aries.

Previous apogeeNext perigee

Distance to Moon 400 773 km

The Moon is 400 773 km (249 029 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 356 877 km (221 753 mi).

Moon after ascending node

3 days after ascending node on 14 September 2015 at 04:38 in ♎ Libra. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 27 September 2015 at 21:04 in ♓ Pisces.

Draconic month

3 days since the beginning of current draconic month in ♎ Libra, the Moon is navigating from the beginning to the first part of the cycle.

Moon before southern standstill

10 days since the previous standstill on 6 September 2015 at 17:06 in ♊ Gemini when the Moon has reached North declination of ∠18.163°, the lunar orbit is extending southward over the next 4 days to face maximum declination of ∠-18.134° at the point of next southern standstill on 21 September 2015 at 12:02 in ♐ Sagittarius.

Syzygy in 10 days

In 10 days on 28 September 2015 at 02:50 in ♈ Aries the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
