Moon phase and lunation details

Moonrise and moonset

Moon rises at noon and sets at midnight. It is visible high in the southern sky in early evening.

Moon in ♐ Sagittarius

Moon is passing about ∠7° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 3.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1903".

Harvest Moon after 7 days

Next Full Moon is the Harvest Moon of September 2030 after 7 days on 11 September 2030 at 21:18.

Upcoming main Moon phases

Neap tide

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.

Lunation 379 / 1332

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 379 of Meeus index or 1332 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

Length of current 379 lunation is 29 days, 10 hours and 47 minutes. It is 25 minutes longer than next lunation 380 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 57 minutes shorter than the mean length of synodic month, but it is still 4 hours and 12 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠279.9°

This lunation true anomaly is ∠279.9°. At the beginning of next synodic month true anomaly will be ∠310.2°. 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 17:06, this is 13 days after last apogee on 21 August 2030 at 22:49 in ♊ Gemini. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 14 days ahead, until it will get to the point of next apogee on 18 September 2030 at 18:09 in ♊ Gemini.

Distance to Moon 369 884 km

This perigee Moon is 369 884 km (229 835 mi) away from Earth. This is the year's farthest perigee of 2030. It is 7 376 km closer than the mean perigee distance, but it is still 472 km farther than the closest perigee of 21st century.

Moon in ascending node

Moon is in ascending node in ♐ Sagittarius at 20:52 on this date, it crosses the ecliptic from South to North. Moon will follow the northern part of its orbit for the next 13 days to meet descending node on 18 September 2030 at 10:12 in ♊ Gemini.

Previous nodeNext node

New draconic month

At 20:52 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

12 days after previous North standstill on 22 August 2030 at 18:22 in ♊ Gemini, when Moon has reached northern declination of ∠22.465°. Next day the lunar orbit moves southward to face South declination of ∠-22.341° in the next southern standstill on 5 September 2030 at 08:00 in ♐ Sagittarius.

Syzygy in 7 days

After 7 days on 11 September 2030 at 21:18 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
