Waning Gibbous on . The illuminated surface of the moon is 83% and getting smaller. The lunar cycle is 18 days old.
The 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.

Main moon phases of the following lunar cycle.
Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Full Moon before 4 days on 2 October 2039 at 07:23.
Next Full Moon is the Hunter Moon of October 2039 after 25 days on 31 October 2039 at 22:36.
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.
Lunar disc appears visually 7.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1774" and ∠1920".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 491 of Meeus index or 1444 from Brown series.
The length of this lunation is 29 days, 10 hours and 46 minutes and it is 9 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 1 hour and 58 minutes shorter than the mean synodic month length. It is 4 hours and 11 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠294.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠321.1°.
13 days since point of perigee on 23 September 2039 at 02:18 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next day until the Moon reaches the point of next apogee on 8 October 2039 at 10:06 in ♊ Gemini.
The Moon is 404 043 km (251 061 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 575 km (251 391 mi).
12 days after descending node on 24 September 2039 at 01:47 in ♐ Sagittarius the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 7 October 2039 at 15:37 in ♊ Gemini.
10 days since the last southern standstill on 25 September 2039 at 19:27 in ♑ Capricorn when the Moon has reached South declination of ∠-25.118° the lunar orbit is extending northward over the next 3 days to face maximum declination of ∠25.247° at the point of next northern standstill on 9 October 2039 at 20:04 in ♋ Cancer.
25 days since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the second to the final part of the lunar cycle.
In 11 days on 17 October 2039 at 19:09 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
