Moon phase and lunation details

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 28 July 2039 at 17:50.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♐ Sagittarius

Moon is passing about ∠15° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1973"

Lunar disc appears visually 4.3% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1890".

Sturgeon Moon after 3 days

Next Full Moon is the Sturgeon Moon of August 2039 after 3 days on 4 August 2039 at 09:56.

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 489 / 1442

The Moon is 10 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 489 of Meeus index or 1442 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.54 days

Length of current 489 lunation is 29 days, 12 hours and 56 minutes. It is 1 hour and 24 minutes longer than next lunation 490 length.

Lunation length longer than mean

Length of current synodic month is 12 minutes longer than the mean length of synodic month, but it is still 6 hours and 51 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠226.3°

This lunation true anomaly is ∠226.3°. At the beginning of next synodic month true anomaly will be ∠260.1°. 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 before perigee

14 days after point of apogee on 17 July 2039 at 03:14 in ♊ Gemini. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next day, until it get to the point of next perigee on 1 August 2039 at 22:38 in ♐ Sagittarius.

Previous apogeeNext perigee

Distance to Moon 363 306 km

Moon is 363 306 km (225 748 mi) away from Earth on this date. Moon moves closer next day until perigee, when Earth-Moon distance will reach 363 901 km (226 118 mi).

Moon in descending node

Moon is in descending node in ♐ Sagittarius at 22:26 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 14 August 2039 at 10:57 in ♊ Gemini.

Draconic month

13 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the middle to the last part of it.

Moon before southern standstill

11 days after previous North standstill on 19 July 2039 at 22:01 in ♋ Cancer, when Moon has reached northern declination of ∠24.697°. Next day the lunar orbit moves southward to face South declination of ∠-24.732° in the next southern standstill on 2 August 2039 at 07:15 in ♑ Capricorn.

Previous standstillNext standstill

Syzygy in 3 days

After 3 days on 4 August 2039 at 09:56 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
