Moon phase and lunation details

7 days after Full Moon

Previous main lunar phase is the Full Moon before 7 days on 2 September 2020 at 05:22.

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 ♊ Gemini

Moon is passing about ∠7° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1794"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1794" and ∠1906".

Harvest Moon before 7 days

Next Full Moon is the Hunter Moon of October 2020 after 22 days on 1 October 2020 at 21:05.

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 255 / 1208

The Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 255 of Meeus index or 1208 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.35 days

The length of the lunation is 29 days, 8 hours and 19 minutes. This is the year's shortest synodic month of 2020. It is 12 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 26 minutes shorter than the mean synodic month length. It is 1 hour and 44 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠322.3°

At the beginning of the lunation cycle the true anomaly is ∠322.3°. At the beginning of next synodic month the true anomaly is going to be ∠341.2°.

Moon after apogee

3 days after point of apogee on 6 September 2020 at 06:31 in ♈ Aries. 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 18 September 2020 at 13:44 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 399 547 km

The Moon is 399 547 km (248 267 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 359 081 km (223 123 mi).

Moon before ascending node

13 days after descending node on 27 August 2020 at 11:52 in ♐ Sagittarius. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 10 September 2020 at 23:05 in ♊ Gemini.

Previous nodeNext node

Draconic month

25 days since the beginning of current draconic month in ♊ Gemini, the Moon is navigating from the second to the final part of the cycle.

Moon before northern standstill

11 days since the previous standstill on 28 August 2020 at 14:06 in ♑ Capricorn when the Moon has reached South declination of ∠-24.219°, the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠24.353° at the point of next northern standstill on 12 September 2020 at 05:25 in ♋ Cancer.

Previous standstillNext standstill

Syzygy in 7 days

In 7 days on 17 September 2020 at 11:00 in ♍ Virgo 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.
