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 ∠17° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1915"

Lunar disc appears visually 0.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1915" and ∠1907".

Harvest Moon after 8 days

Next Full Moon is the Harvest Moon of September 2002 after 8 days on 21 September 2002 at 13:59.

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.

The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 33 of Meeus index or 986 from Brown series.

Synodic month length 29.34 days

Length of current 33 lunation is 29 days, 8 hours and 7 minutes. It is 1 hour and 10 minutes shorter than next lunation 34 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 37 minutes shorter than the mean length of synodic month, but it is still 1 hour and 32 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠343.1°

This lunation true anomaly is ∠343.1°. At the beginning of next synodic month true anomaly will be ∠358.6°. 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

5 days after point of perigee on 8 September 2002 at 03:14 in ♍ Virgo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 23 September 2002 at 03:26 in ♈ Aries.

Distance to Moon 374 295 km

Moon is 374 295 km (232 576 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 406 351 km (252 495 mi).

Moon in descending node

Moon is in descending node in ♐ Sagittarius at 03:39 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 14 days to meet ascending node on 27 September 2002 at 16:06 in ♊ Gemini.

Moon before southern standstill

10 days after previous North standstill on 2 September 2002 at 16:03 in ♋ Cancer, when Moon has reached northern declination of ∠25.282°. Next day the lunar orbit moves southward to face South declination of ∠-25.377° in the next southern standstill on 15 September 2002 at 05:34 in ♑ Capricorn.

Syzygy in 8 days

After 8 days on 21 September 2002 at 13:59 in ♓ Pisces, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
