Moon phase and lunation details

Moonrise and moonset

Moon rises at midnight and sets at noon. It is visible to the south in the morning.

Moon in ♊ Gemini

Moon is passing about ∠11° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1784"

Lunar disc appears visually 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1784" and ∠1900".

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2100 after 20 days on 18 September 2100 at 11:32.

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 1244 / 2197

The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 1244 of Meeus index or 2197 from Brown series.

Synodic month length 29.41 days

Length of current 1244 lunation is 29 days, 9 hours and 48 minutes. It is 35 minutes longer than next lunation 1245 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 56 minutes shorter than the mean length of synodic month, but it is still 3 hours and 13 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠294.6°

This lunation true anomaly is ∠294.6°. At the beginning of next synodic month true anomaly will be ∠320.8°. 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 apogee

2 days after point of apogee on 25 August 2100 at 23:00 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 6 September 2100 at 19:23 in ♎ Libra.

Distance to Moon 401 804 km

Moon is 401 804 km (249 669 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 363 868 km (226 097 mi).

Moon before descending node

7 days after its ascending node on 20 August 2100 at 18:39 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 4 September 2100 at 02:42 in ♍ Virgo.

Moon before northern standstill

13 days after previous South standstill on 15 August 2100 at 09:13 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.334°. Next day the lunar orbit moves northward to face North declination of ∠28.356° in the next northern standstill on 29 August 2100 at 17:37 in ♊ Gemini.

Syzygy in 6 days

After 6 days on 4 September 2100 at 08:49 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
