Moon phase and lunation details

1 day after New Moon

Previous main lunar phase is the New Moon before 1 day on 20 September 2017 at 05:30.

Moonrise and moonset

Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.

The length of the lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 48 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 longer than mean

The length of the current synodic month is 58 minutes longer than the mean synodic month length. It is 6 hours and 5 minutes shorter compared to 21st century's longest synodic month length.

Moon after ascending node

3 days after ascending node on 17 September 2017 at 18:28 in ♌ Leo. The Moon is located north of the ecliptic over the following 10 days, until the lunar orbit crosses from North to South in descending node on 2 October 2017 at 02:05 in ♒ Aquarius.

Moon before southern standstill

6 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 6 days to face maximum declination of ∠-19.516° at the point of next southern standstill on 28 September 2017 at 10:06 in ♑ Capricorn.

Syzygy in 14 days

In 14 days on 5 October 2017 at 18:40 in ♈ Aries the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
