Upcoming main Moon phases
- Full Moon in Aquarius ♒ on 3 August 2031 at 01:45
- Last Quarter in Taurus ♉ on 10 August 2031 at 00:24
- New Moon in Leo ♌ on 18 August 2031 at 04:32

Spring tide
There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.
Lunation 390 / 1343
The Moon is 14 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 390 of Meeus index or 1343 from Brown series.
Synodic month length 29.62 days
Length of current 390 lunation is 29 days, 14 hours and 52 minutes. It is 37 minutes longer than next lunation 391 length.
Lunation length longer than mean
Length of current synodic month is 2 hours and 8 minutes longer than the mean length of synodic month, but it is still 4 hours and 55 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠188.7°
This lunation true anomaly is ∠188.7°. At the beginning of next synodic month true anomaly will be ∠213.5°. 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°).
Moon in perigee
Moon is reaching point of perigee on this date at 06:47, this is 14 days after last apogee on 18 July 2031 at 14:28 in ♋ Cancer. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 12 days ahead, until it will get to the point of next apogee on 14 August 2031 at 21:37 in ♋ Cancer.
Distance to Moon 358 060 km
This perigee Moon is 358 060 km (222 488 mi) away from Earth. It is 4 448 km closer than the mean perigee distance, but it is still 12 296 km farther than the closest perigee of 21st century.
Moon after ascending node
4 days after its ascending node on 28 July 2031 at 23:54 in ♏ Scorpio, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 10 August 2031 at 14:10 in ♉ Taurus.
Draconic month
4 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the beginning to the first part of it.
Moon after southern standstill
2 days after previous South standstill on 30 July 2031 at 15:45 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.951°. Next 10 days the lunar orbit moves northward to face North declination of ∠20.868° in the next northern standstill on 12 August 2031 at 15:58 in ♊ Gemini.
Sun-Earth-Moon syzygy
The Moon is in Full Moon geocentric opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
