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 220 / 1173
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 220 of Meeus index or 1173 from Brown series.
Synodic month length 29.69 days
Length of current 220 lunation is 29 days, 16 hours and 30 minutes. It is 2 hours and 18 minutes shorter than next lunation 221 length.
Lunation length longer than mean
Length of current synodic month is 3 hours and 46 minutes longer than the mean length of synodic month, but it is still 3 hours and 17 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠114.6°
This New Moon true anomaly is ∠114.6°. At beginning of next synodic month true anomaly will be ∠147°. 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 apogee
2 days after point of apogee on 25 October 2017 at 02:25 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 6 November 2017 at 00:09 in ♊ Gemini.
Distance to Moon 402 134 km
Moon is 402 134 km (249 874 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 361 438 km (224 587 mi).
Moon before descending node
12 days after its ascending node on 14 October 2017 at 22:10 in ♌ Leo, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 29 October 2017 at 06:41 in ♒ Aquarius.
Draconic month
12 days after beginning of current draconic month in ♌ Leo, the Moon is moving from the beginning to the first part of it.
Moon after southern standstill
1 day after previous South standstill on 25 October 2017 at 18:13 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.741°. Next 11 days the lunar orbit moves northward to face North declination of ∠19.848° in the next northern standstill on 8 November 2017 at 01:28 in ♋ Cancer.
Syzygy in 7 days
After 7 days on 4 November 2017 at 05:23 in ♉ Taurus, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
