Moon phase and lunation details

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 13 September 2017 at 06:25.

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.

Synodic month length 29.46 days

The length of the lunation is 29 days, 11 hours and 1 minute. It is 2 hours and 42 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 1 hour and 44 minutes shorter than the mean synodic month length. It is 4 hours and 25 minutes longer compared to 21st century's shortest synodic month length.

Distance to Moon 372 085 km

The Moon is 372 085 km (231 203 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 404 342 km (251 246 mi).

Moon after northern standstill

2 days since the previous standstill on 14 September 2017 at 13:00 in ♋ Cancer when the Moon has reached North declination of ∠19.438°, the lunar orbit is extending southward over the next 10 days to face maximum declination of ∠-19.516° at the point of next southern standstill on 28 September 2017 at 10:06 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 2 days

In 2 days on 20 September 2017 at 05:30 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.
