Moon phase and lunation details

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 28 August 2007 at 10:35.

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 ∠19° of ♈ Aries tropical zodiac sector.

Apparent angular diameter ∠1969"

Lunar disc appears visually 3.5% wider than solar disc. Moon and Sun apparent angular diameters are ∠1969" and ∠1901".

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2007 after 26 days on 26 September 2007 at 19:45.

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 94 / 1047

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 94 of Meeus index or 1047 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.57 days

Length of current 94 lunation is 29 days, 13 hours and 42 minutes. It is 2 hours and 34 minutes shorter than next lunation 95 length.

Lunation length longer than mean

Length of current synodic month is 58 minutes longer than the mean length of synodic month, but it is still 6 hours and 5 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠97.3°

This New Moon true anomaly is ∠97.3°. At beginning of next synodic month true anomaly will be ∠131.4°. 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 in perigee

Moon is reaching point of perigee on this date at 00:12, this is 11 days after last apogee on 19 August 2007 at 03:28 in ♏ Scorpio. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 15 days ahead, until it will get to the point of next apogee on 15 September 2007 at 21:06 in ♏ Scorpio.

Distance to Moon 364 174 km

This perigee Moon is 364 174 km (226 287 mi) away from Earth. It is 1 666 km closer than the mean perigee distance, but it is still 6 182 km farther than the closest perigee of 21st century.

Moon after ascending node

2 days after its ascending node on 28 August 2007 at 14:27 in ♒ Aquarius, 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 10 September 2007 at 14:49 in ♍ Virgo.

Draconic month

2 days after beginning of current draconic month in ♒ Aquarius, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

8 days after previous South standstill on 23 August 2007 at 08:02 in ♐ Sagittarius, when Moon has reached southern declination of ∠-28.377°. Next 4 days the lunar orbit moves northward to face North declination of ∠28.380° in the next northern standstill on 5 September 2007 at 04:28 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 11 September 2007 at 12:44 in ♍ Virgo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
