Moon phase and lunation details

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 2 September 2020 at 05:22.

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 ∠8° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1772"

Lunar disc appears visually 7.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1772" and ∠1903".

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2020 after 27 days on 1 October 2020 at 21:05.

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 255 / 1208

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 255 of Meeus index or 1208 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.35 days

Length of current 255 lunation is 29 days, 8 hours and 19 minutes. This is the year's shortest synodic month of 2020. It is 12 minutes shorter than next lunation 256 length.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 26 minutes shorter than the mean length of synodic month, but it is still 1 hour and 44 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠322.3°

This lunation true anomaly is ∠322.3°. At the beginning of next synodic month true anomaly will be ∠341.2°. 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

14 days after point of perigee on 21 August 2020 at 10:59 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next day, until it get to the point of next apogee on 6 September 2020 at 06:31 in ♈ Aries.

Distance to Moon 404 495 km

Moon is 404 495 km (251 342 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 606 km (252 032 mi).

Moon before ascending node

8 days after its descending node on 27 August 2020 at 11:52 in ♐ Sagittarius, the Moon is following the southern part of its orbit for the next 6 days, until it will cross the ecliptic from South to North in ascending node on 10 September 2020 at 23:05 in ♊ Gemini.

Draconic month

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

Moon after southern standstill

6 days after previous South standstill on 28 August 2020 at 14:06 in ♑ Capricorn, when Moon has reached southern declination of ∠-24.219°. Next 7 days the lunar orbit moves northward to face North declination of ∠24.353° in the next northern standstill on 12 September 2020 at 05:25 in ♋ Cancer.

Syzygy in 12 days

After 12 days on 17 September 2020 at 11:00 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
