Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 20 September 2011 at 13:39.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♋ Cancer

Moon is passing about ∠22° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1875"

Lunar disc appears visually 1.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1875" and ∠1912".

Hunter Moon after 19 days

Next Full Moon is the Hunter Moon of October 2011 after 19 days on 12 October 2011 at 02:06.

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 144 / 1097

The Moon is 24 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.

Synodic month length 29.34 days

The length of the lunation is 29 days, 8 hours and 5 minutes. This is the year's shortest synodic month of 2011. It is 42 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 shorter than mean

The length of the current synodic month is 4 hours and 39 minutes shorter than the mean synodic month length. It is 1 hour and 30 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠333.4°

At the beginning of the lunation cycle the true anomaly is ∠333.4°. At the beginning of next synodic month the true anomaly is going to be ∠350.1°.

Moon before apogee

7 days after point of apogee on 15 September 2011 at 06:23 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 5 days, until the Moon reaches the point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 382 216 km

The Moon is 382 216 km (237 498 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 357 556 km (222 175 mi).

Moon after descending node

2 days after descending node on 19 September 2011 at 19:38 in ♊ Gemini. The Moon is located south of the ecliptic over the following 9 days, until the lunar orbit crosses from South to North in ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius.

Draconic month

17 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

2 days since the previous standstill on 19 September 2011 at 20:05 in ♊ Gemini when the Moon has reached North declination of ∠22.890°, the lunar orbit is extending southward over the next 9 days to face maximum declination of ∠-22.791° at the point of next southern standstill on 2 October 2011 at 11:38 in ♐ Sagittarius.

Syzygy in 4 days

In 4 days on 27 September 2011 at 11:09 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.
