Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 5 October 2017 at 18:40.

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.

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 219 of Meeus index or 1172 from Brown series.

Synodic month length 29.57 days

Length of current 219 lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 48 minutes shorter than next lunation 220 length.

Lunation length longer than mean

Length of current synodic month is 58 minutes longer than the mean length of synodic month, but it is still 6 hours and 5 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠79°

This New Moon true anomaly is ∠79°. At beginning of next synodic month true anomaly will be ∠114.6°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after perigee

1 day after point of perigee on 9 October 2017 at 05:51 in ♊ Gemini. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 14 days, until it get to the point of next apogee on 25 October 2017 at 02:25 in ♑ Capricorn.

Moon before northern standstill

12 days after previous South standstill on 28 September 2017 at 10:06 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.516°. Next day the lunar orbit moves northward to face North declination of ∠19.616° in the next northern standstill on 11 October 2017 at 18:21 in ♋ Cancer.

Syzygy in 9 days

After 9 days on 19 October 2017 at 19:12 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
