Waning Gibbous on . The illuminated surface of the moon is 87% 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 about ∠14° of ♊ Gemini tropical zodiac sector.
Previous main lunar phase is the Full Moon before 3 days on 20 October 2021 at 14:57.
Next Full Moon is the Beaver Moon of November 2021 after 25 days on 19 November 2021 at 08:58.
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 8.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1930".
The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 269 of Meeus index or 1222 from Brown series.
The length of this lunation is 29 days, 10 hours and 9 minutes and it is 19 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2021. 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 2 hours and 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 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 ∠323.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠342.3°.
Moon is at apogee at 15:30 about 15 days since last perigee on 8 October 2021 at 17:28 in ♏ Scorpio the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 12 days until point of next perigee on 5 November 2021 at 22:23 in ♏ Scorpio.
This apogee Moon is 405 616 km (252 038 mi) away from Earth. It is 208 km further than the mean apogee distance, but it is still 1 093 km closer than the farthest apogee of 21st century.
1 day after ascending node on 23 October 2021 at 11:47 in ♊ Gemini the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 6 November 2021 at 03:38 in ♐ Sagittarius.
12 days since the last southern standstill on 12 October 2021 at 09:09 in ♑ Capricorn when the Moon has reached South declination of ∠-26.204° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.291° at the point of next northern standstill on 26 October 2021 at 16:04 in ♋ Cancer.
1 day since the beginning of this draconic month in ♊ Gemini the Moon is navigating from the beginning to the first part of the lunar cycle.
In 11 days on 4 November 2021 at 21:15 in ♏ Scorpio 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.
