Moon phase and lunation details

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 29 September 2023 at 09:57.

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 ∠17° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1840"

Lunar disc appears visually 4.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1840" and ∠1918".

Harvest Moon before 5 days

Next Full Moon is the Hunter Moon of October 2023 after 24 days on 28 October 2023 at 20:24.

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 293 / 1246

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 293 of Meeus index or 1246 from Brown series.

Synodic month length 29.68 days

Length of current 293 lunation is 29 days, 16 hours and 15 minutes. This is the year's longest synodic month of 2023. It is 43 minutes longer than next lunation 294 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 31 minutes longer than the mean length of synodic month, but it is still 3 hours and 32 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠202.9°

This lunation true anomaly is ∠202.9°. At the beginning of next synodic month true anomaly will be ∠232.5°. 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 before apogee

6 days after point of perigee on 28 September 2023 at 01:05 in ♓ Pisces. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 10 October 2023 at 03:41 in ♌ Leo.

Distance to Moon 389 503 km

Moon is 389 503 km (242 026 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 405 426 km (251 920 mi).

Moon after ascending node

3 days after its ascending node on 30 September 2023 at 16:49 in ♈ Aries, the Moon is following the northern part of its orbit for the next 10 days, until it will cross the ecliptic from North to South in descending node on 15 October 2023 at 01:11 in ♎ Libra.

Draconic month

3 days after beginning of current draconic month in ♈ Aries, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

11 days after previous South standstill on 23 September 2023 at 03:42 in ♑ Capricorn, when Moon has reached southern declination of ∠-28.254°. Next day the lunar orbit moves northward to face North declination of ∠28.294° in the next northern standstill on 5 October 2023 at 20:31 in ♊ Gemini.

Syzygy in 10 days

After 10 days on 14 October 2023 at 17:55 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
