Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 30 September 2012 at 03:19.

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 is entering ♊ Gemini

Moon is passing first ∠0° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 8.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1919".

Harvest Moon before 4 days

Next Full Moon is the Hunter Moon of October 2012 after 25 days on 29 October 2012 at 19:50.

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 157 / 1110

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 157 of Meeus index or 1110 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.41 days

Length of current 157 lunation is 29 days, 9 hours and 52 minutes. This is the year's shortest synodic month of 2012. It is 13 minutes shorter than next lunation 158 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 52 minutes shorter than the mean length of synodic month, but it is still 3 hours and 17 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠312.9°

This lunation true anomaly is ∠312.9°. At the beginning of next synodic month true anomaly will be ∠334.3°. 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

15 days after point of perigee on 19 September 2012 at 02:52 in ♏ Scorpio. 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 5 October 2012 at 00:43 in ♊ Gemini.

Distance to Moon 405 481 km

Moon is 405 481 km (251 954 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 405 162 km (251 756 mi).

Moon in descending node

Moon is in descending node in ♉ Taurus at 05:15 on this date, it crosses the ecliptic from North to South. Moon will follow the southern part of its orbit for the next 13 days to meet ascending node on 17 October 2012 at 18:27 in ♏ Scorpio.

Draconic month

13 days after beginning of current draconic month in ♏ Scorpio, the Moon is moving from the second to the final part of it.

Moon before northern standstill

12 days after previous South standstill on 22 September 2012 at 00:11 in ♐ Sagittarius, when Moon has reached southern declination of ∠-21.135°. Next day the lunar orbit moves northward to face North declination of ∠21.024° in the next northern standstill on 6 October 2012 at 01:40 in ♊ Gemini.

Syzygy in 11 days

After 11 days on 15 October 2012 at 12:02 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
