Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 2 September 2001 at 21:43.

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 ♈ Aries

Moon is passing about ∠24° of ♈ Aries tropical zodiac sector.

Harvest Moon before 3 days

Next Full Moon is the Hunter Moon of October 2001 after 26 days on 2 October 2001 at 13:49.

Upcoming main Moon phases

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 18 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 20 of Meeus index or 973 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.31 days

Length of current 20 lunation is 29 days, 7 hours and 32 minutes. It is 1 hour and 24 minutes shorter than next lunation 21 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 12 minutes shorter than the mean length of synodic month, but it is still 57 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠358.1°

This New Moon true anomaly is ∠358.1°. At beginning of next synodic month true anomaly will be ∠13.2°. 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 1 September 2001 at 23:26 in ♒ Aquarius. 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 16 September 2001 at 15:50 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 396 827 km

Moon is 396 827 km (246 577 mi) away from Earth on this date. Moon moves closer next 10 days until perigee, when Earth-Moon distance will reach 358 128 km (222 530 mi).

Moon before ascending node

9 days after its descending node on 28 August 2001 at 09:09 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 11 September 2001 at 21:36 in ♊ Gemini.

Draconic month

21 days after beginning of current draconic month in ♊ Gemini, the Moon is moving from the second to the final part of it.

Moon before northern standstill

8 days after previous South standstill on 28 August 2001 at 23:14 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.546°. Next 6 days the lunar orbit moves northward to face North declination of ∠23.677° in the next northern standstill on 12 September 2001 at 12:19 in ♋ Cancer.

Syzygy in 10 days

After 10 days on 17 September 2001 at 10:27 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
