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 15 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 after perigee
1 day after point of perigee on 2 August 2031 at 06:47 in ♑ Capricorn. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 11 days, until it get to the point of next apogee on 14 August 2031 at 21:37 in ♋ Cancer.
Distance to Moon 365 581 km
Moon is 365 581 km (227 162 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 405 946 km (252 243 mi).
Moon after ascending node
5 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 7 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
5 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
3 days after previous South standstill on 30 July 2031 at 15:45 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.951°. Next 9 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.
