Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 18 September 2081 at 03:45.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon in ♉ Taurus

Moon is passing about ∠6° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1800"

Lunar disc appears visually 6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1800" and ∠1912".

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2081 after 26 days on 17 October 2081 at 20:50.

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 1010 / 1963

The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 1010 of Meeus index or 1963 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.35 days

Length of current 1010 lunation is 29 days, 8 hours and 22 minutes. It is 1 hour and 19 minutes shorter than next lunation 1011 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 22 minutes shorter than the mean length of synodic month, but it is still 1 hour and 47 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠357.1°

This New Moon true anomaly is ∠357.1°. At beginning of next synodic month true anomaly will be ∠12.5°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

4 days after point of apogee on 17 September 2081 at 08:20 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 1 October 2081 at 23:44 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 398 188 km

Moon is 398 188 km (247 423 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 358 089 km (222 506 mi).

Moon after ascending node

4 days after its ascending node on 17 September 2081 at 06:18 in ♓ Pisces, the Moon is following the northern part of its orbit for the next 9 days, until it will cross the ecliptic from North to South in descending node on 1 October 2081 at 01:46 in ♍ Virgo.

Draconic month

4 days after beginning of current draconic month in ♓ Pisces, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

10 days after previous South standstill on 10 September 2081 at 20:08 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.547°. Next 4 days the lunar orbit moves northward to face North declination of ∠28.512° in the next northern standstill on 25 September 2081 at 14:31 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 2 October 2081 at 17:23 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
