Moon rises at sunrise and sets at sunset. It's part facing the Earth is completely in shadow.
Lunar disc is not visible from Earth. Moon and Sun apparent angular diameters are ∠1781" and ∠1908".
Next Full Moon is the Harvest Moon of September 2023 after 13 days on 29 September 2023 at 09:57.
There is high New Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.
At 01:40 on this date the Moon completes the old and enters a new synodic month with lunation 293 of Meeus index or 1246 from Brown series.
29 days, 16 hours and 15 minutes is the length of new lunation 293. This is the year's longest synodic month of 2023. It is 43 minutes longer than next lunation 294 length.
Length of current synodic month is 3 hours and 31 minutes longer than the mean length of synodic month, but it is still 3 hours and 32 minutes shorter, compared to 21st century longest.
This lunation true anomaly is ∠202.9°. At the beginning of next synodic month true anomaly will be ∠232.5°. 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°).
2 days after point of apogee on 12 September 2023 at 15:42 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 12 days, until it get to the point of next perigee on 28 September 2023 at 01:05 in ♓ Pisces.
Moon is 402 536 km (250 124 mi) away from Earth on this date. Moon moves closer next 12 days until perigee, when Earth-Moon distance will reach 359 911 km (223 638 mi).
12 days after its ascending node on 3 September 2023 at 07:44 in ♈ Aries, the Moon is following the northern part of its orbit for the next 2 days, until it will cross the ecliptic from North to South in descending node on 17 September 2023 at 19:18 in ♎ Libra.

6 days after previous North standstill on 8 September 2023 at 13:18 in ♊ Gemini, when Moon has reached northern declination of ∠28.168°. Next 7 days the lunar orbit moves southward to face South declination of ∠-28.254° in the next southern standstill on 23 September 2023 at 03:42 in ♑ Capricorn.
The Moon is in New Moon geocentric conjunction with the Sun on this date and this alignment forms Sun-Moon-Earth syzygy.
