Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 11 September 2030 at 21:18.

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 leaving the last ∠1° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Apparent angular diameter ∠1770"

Lunar disc appears visually 7.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1909".

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2030 after 23 days on 11 October 2030 at 10:47.

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 379 / 1332

The Moon is 20 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 379 of Meeus index or 1332 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

The length of the lunation is 29 days, 10 hours and 47 minutes. It is 25 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 1 hour and 57 minutes shorter than the mean synodic month length. It is 4 hours and 12 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠279.9°

At the beginning of the lunation cycle the true anomaly is ∠279.9°. At the beginning of next synodic month the true anomaly is going to be ∠310.2°.

Moon before perigee

12 days after point of perigee on 4 September 2030 at 17:06 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next day, until the Moon reaches the point of next apogee on 18 September 2030 at 18:09 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 404 843 km

The Moon is 404 843 km (251 558 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 404 258 km (251 194 mi).

Moon before descending node

12 days after ascending node on 4 September 2030 at 20:52 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following day, until the lunar orbit crosses from North to South in descending node on 18 September 2030 at 10:12 in ♊ Gemini.

Draconic month

12 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon before northern standstill

12 days since the previous standstill on 5 September 2030 at 08:00 in ♐ Sagittarius when the Moon has reached South declination of ∠-22.341°, the lunar orbit is extending northward over the next day to face maximum declination of ∠22.208° at the point of next northern standstill on 19 September 2030 at 02:24 in ♊ Gemini.

Syzygy in 9 days

In 9 days on 27 September 2030 at 09:55 in ♎ Libra the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
