Lunar orbit position on

True anomaly ∠49.5°

Moon after southern standstill

6 days after previous South standstill on 1 September 2017 at 02:03 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 7 days the lunar orbit moves northward to face North declination of ∠19.438° in the next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.
