Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 15 August 2017 at 01:15.

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 ♊ Gemini

Moon is passing about ∠13° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1972"

Lunar disc appears visually 4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1895".

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2017 after 20 days on 6 September 2017 at 07:03.

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 217 / 1170

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.36 days

The length of the lunation is 29 days, 8 hours and 45 minutes. It is 2 hours and 15 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 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠27.9°

At the beginning of the lunation cycle the true anomaly is ∠27.9°. At the beginning of next synodic month the true anomaly is going to be ∠49.5°.

Moon before apogee

13 days after point of apogee on 2 August 2017 at 17:55 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 2 days, until the Moon reaches the point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 363 436 km

The Moon is 363 436 km (225 829 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 366 129 km (227 502 mi).

Moon before ascending node

8 days after descending node on 8 August 2017 at 10:56 in ♒ Aquarius. The Moon is located south of the ecliptic over the following 4 days, until the lunar orbit crosses from South to North in ascending node on 21 August 2017 at 10:34 in ♌ Leo.

Draconic month

22 days since the beginning of current draconic month in ♍ Virgo, 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 4 August 2017 at 18:17 in ♑ Capricorn when the Moon has reached South declination of ∠-19.393°, the lunar orbit is extending northward over the next day to face maximum declination of ∠19.381° at the point of next northern standstill on 18 August 2017 at 06:50 in ♋ Cancer.

Syzygy in 5 days

In 5 days on 21 August 2017 at 18:30 in ♌ Leo 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.
