Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 29 October 2012 at 19:50.

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 ♉ Taurus

Moon is leaving the last ∠3° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Apparent angular diameter ∠1769"

Lunar disc appears visually 8.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1769" and ∠1933".

Hunter Moon before 1 day

Next Full Moon is the Beaver Moon of November 2012 after 28 days on 28 November 2012 at 14:46.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 158 / 1111

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 158 of Meeus index or 1111 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.42 days

Length of current 158 lunation is 29 days, 10 hours and 5 minutes. It is 29 minutes shorter than next lunation 159 length.

Lunation length shorter than mean

Length of current synodic month is 2 hours and 39 minutes shorter than the mean length of synodic month, but it is still 3 hours and 30 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠334.3°

This lunation true anomaly is ∠334.3°. At the beginning of next synodic month true anomaly will be ∠351.3°. 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

14 days after point of perigee on 17 October 2012 at 01:02 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 1 November 2012 at 15:30 in ♊ Gemini.

Previous perigeeNext apogee

Distance to Moon 405 231 km

Moon is 405 231 km (251 799 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 406 050 km (252 308 mi).

Moon in descending node

Moon is in descending node in ♉ Taurus at 10:36 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 14 November 2012 at 04:37 in ♏ Scorpio.

Previous nodeNext node

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 19 October 2012 at 06:49 in ♐ Sagittarius, when Moon has reached southern declination of ∠-20.964°. Next day the lunar orbit moves northward to face North declination of ∠20.920° in the next northern standstill on 2 November 2012 at 08:15 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 13 days

After 13 days on 13 November 2012 at 22:08 in ♏ Scorpio, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
