Moon phase and lunation details

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 2 October 2039 at 07:23.

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 ♊ Gemini

Moon is passing about ∠25° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 8.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1921".

Hunter Moon before 6 days

Next Full Moon is the Hunter Moon of October 2039 after 23 days on 31 October 2039 at 22:36.

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 491 / 1444

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 491 of Meeus index or 1444 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.45 days

The length of the lunation is 29 days, 10 hours and 46 minutes. It is 9 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 58 minutes shorter than the mean synodic month length. It is 4 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠294.5°

At the beginning of the lunation cycle the true anomaly is ∠294.5°. At the beginning of next synodic month the true anomaly is going to be ∠321.1°.

Moon at apogee

Moon is at apogee at 10:06. It is 15 days after previous perigee on 23 September 2039 at 02:18 in ♐ Sagittarius. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 11 days, until point of next perigee on 20 October 2039 at 05:11 in ♏ Scorpio.

Previous perigeeNext perigee

Distance to Moon 404 575 km

This apogee Moon is 404 575 km (251 391 mi) away from Earth. It is 833 km further than the mean apogee distance, but it is still 2 134 km closer than the farthest apogee of 21st century.

Moon after ascending node

1 day after ascending node on 7 October 2039 at 15:37 in ♊ Gemini. The Moon is located north of the ecliptic over the following 12 days, until the lunar orbit crosses from North to South in descending node on 21 October 2039 at 04:37 in ♐ Sagittarius.

Draconic month

1 day since the beginning of current draconic month in ♊ Gemini, 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 25 September 2039 at 19:27 in ♑ Capricorn when the Moon has reached South declination of ∠-25.118°, the lunar orbit is extending northward over the next day to face maximum declination of ∠25.247° at the point of next northern standstill on 9 October 2039 at 20:04 in ♋ Cancer.

Syzygy in 9 days

In 9 days on 17 October 2039 at 19:09 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.
