Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♋ Cancer

Moon is passing about ∠8° of ♋ Cancer tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1915".

Hunter Moon after 21 days

Next Full Moon is the Hunter Moon of October 2013 after 21 days on 18 October 2013 at 23:38.

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 169 / 1122

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.

Synodic month length 29.54 days

The length of the lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer 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 14 minutes longer than the mean synodic month length. It is 6 hours and 49 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠249.2°

At the beginning of the lunation cycle the true anomaly is ∠249.2°. At the beginning of next synodic month the true anomaly is going to be ∠285.3°.

Moon at apogee

Moon is at apogee at 18:17. It is 12 days after previous perigee on 15 September 2013 at 16:34 in ♑ Capricorn. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 13 days, until point of next perigee on 10 October 2013 at 23:06 in ♐ Sagittarius.

Distance to Moon 404 309 km

This apogee Moon is 404 309 km (251 226 mi) away from Earth. It is 1 099 km further than the mean apogee distance, but it is still 2 400 km closer than the farthest apogee of 21st century.

Moon after descending node

4 days after descending node on 22 September 2013 at 13:48 in ♉ Taurus. 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 6 October 2013 at 22:08 in ♏ Scorpio.

Moon after northern standstill

1 day since the previous standstill on 26 September 2013 at 01:03 in ♊ Gemini when the Moon has reached North declination of ∠19.599°, the lunar orbit is extending southward over the next 12 days to face maximum declination of ∠-19.537° at the point of next southern standstill on 9 October 2013 at 23:52 in ♐ Sagittarius.

Syzygy in 7 days

In 7 days on 5 October 2013 at 00:35 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.
