Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 25 September 2018 at 02:53.

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 in ♈ Aries

Moon is passing about ∠20° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1842"

Lunar disc appears visually 3.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1842" and ∠1914".

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2018 after 28 days on 24 October 2018 at 16:45.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 231 / 1184

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 231 of Meeus index or 1184 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 45 minutes. It is 2 hours and 30 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 shorter than mean

The length of the current synodic month is 2 hours and 59 minutes shorter than the mean synodic month length. It is 3 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠28°

At the beginning of the lunation cycle the true anomaly is ∠28°. At the beginning of next synodic month the true anomaly is going to be ∠49.6°.

Moon after apogee

6 days after point of apogee on 20 September 2018 at 00:54 in ♒ Aquarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 5 October 2018 at 22:29 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 389 196 km

The Moon is 389 196 km (241 835 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 366 396 km (227 668 mi).

Moon after descending node

6 days after descending node on 20 September 2018 at 09:30 in ♒ Aquarius. 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 4 October 2018 at 03:10 in ♌ Leo.

Draconic month

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

Moon before northern standstill

8 days since the previous standstill on 18 September 2018 at 09:35 in ♑ Capricorn when the Moon has reached South declination of ∠-20.909°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠21.037° at the point of next northern standstill on 2 October 2018 at 13:03 in ♋ Cancer.

Syzygy in 12 days

In 12 days on 9 October 2018 at 03:47 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.
