Waning Gibbous on . The illuminated surface of the moon is 76% and getting smaller. The lunar cycle is 19 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 leaving the last ∠2° of ♊ Gemini tropical zodiac sector and will enter ♋ Cancer later.
Previous main lunar phase is the Full Moon before 5 days on 18 October 2100 at 04:06.
Next Full Moon is the Beaver Moon of November 2100 after 24 days on 16 November 2100 at 22:19.
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 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1795" and ∠1929".
The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 1246 of Meeus index or 2199 from Brown series.
The length of this lunation is 29 days, 9 hours and 12 minutes and it is 34 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2100. 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 3 hours and 32 minutes shorter than the mean synodic month length. It is 2 hours and 37 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 ∠340.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠356.4°.
3 days since point of apogee on 20 October 2100 at 04:03 in ♉ Taurus the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 2 November 2100 at 08:19 in ♏ Scorpio.
The Moon is 399 371 km (248 158 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 356 834 km (221 726 mi).
9 days after ascending node on 14 October 2100 at 06:36 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 28 October 2100 at 20:12 in ♌ Leo.
At 08:12 the Moon is meeting its standstill point to reach North declination of ∠28.129°. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.051° at the point of next southern standstill in ♐ Sagittarius on 5 November 2100 at 05:15.
9 days since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.
In 9 days on 2 November 2100 at 03:14 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.
