Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 268 / 1221
The Moon is 14 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 268 of Meeus index or 1221 from Brown series.
Synodic month length 29.43 days
Length of current 268 lunation is 29 days, 10 hours and 14 minutes. It is 5 minutes longer than next lunation 269 length.
Lunation length shorter than mean
Length of current synodic month is 2 hours and 30 minutes shorter than the mean length of synodic month, but it is still 3 hours and 39 minutes longer, compared to 21st century shortest.
Lunar orbit position on
True anomaly ∠297.8°
This lunation true anomaly is ∠297.8°. At the beginning of next synodic month true anomaly will be ∠323.3°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).
Moon before apogee
9 days after point of perigee on 11 September 2021 at 10:05 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 6 days, until it get to the point of next apogee on 26 September 2021 at 21:44 in ♊ Gemini.
Distance to Moon 388 845 km
Moon is 388 845 km (241 617 mi) away from Earth on this date. Moon moves farther next 6 days until apogee, when Earth-Moon distance will reach 404 641 km (251 432 mi).
Moon before ascending node
7 days after its descending node on 12 September 2021 at 16:35 in ♏ Scorpio, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 26 September 2021 at 07:33 in ♊ Gemini.
Draconic month
21 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.
Moon after southern standstill
5 days after previous South standstill on 15 September 2021 at 03:48 in ♑ Capricorn, when Moon has reached southern declination of ∠-25.980°. Next 8 days the lunar orbit moves northward to face North declination of ∠26.109° in the next northern standstill on 29 September 2021 at 08:26 in ♋ Cancer.
Sun-Earth-Moon syzygy
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
