Gibbous ♈ Aries
Waning Gibbous is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 84% and getting smaller. The 18 days old Moon is in ♈ Aries.
Previous main lunar phase is the Full Moon before 3 days on 3 August 2031 at 01:45.
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.
Moon is passing first ∠1° of ♈ Aries tropical zodiac sector.
Lunar disc appears visually 0.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1903" and ∠1892".
Next Full Moon is the Harvest Moon of September 2031 after 25 days on 1 September 2031 at 09:20.
There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.
The Moon is 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.
The length of the lunation is 29 days, 14 hours and 52 minutes. It is 37 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the 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 8 minutes longer than the mean synodic month length. It is 4 hours and 55 minutes shorter compared to 21st century's longest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠188.7°. At the beginning of next synodic month the true anomaly is going to be ∠213.5°.
4 days after point of perigee on 2 August 2031 at 06:47 in ♑ Capricorn. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 8 days, until the Moon reaches the point of next apogee on 14 August 2031 at 21:37 in ♋ Cancer.
The Moon is 376 624 km (234 023 mi) away from Earth and getting further over the next 8 days until the point apogee when Earth-Moon distance is going to be 405 946 km (252 243 mi).
8 days after ascending node on 28 July 2031 at 23:54 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 10 August 2031 at 14:10 in ♉ Taurus.
8 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
6 days since the previous standstill on 30 July 2031 at 15:45 in ♐ Sagittarius when the Moon has reached South declination of ∠-20.951°, the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠20.868° at the point of next northern standstill on 12 August 2031 at 15:58 in ♊ Gemini.
In 11 days on 18 August 2031 at 04:32 in ♌ Leo 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.
