Moon phase and lunation details

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.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 30 September 2012 at 03:19.

Moon in ♈ Aries

Moon is passing about ∠24° of ♈ Aries tropical zodiac sector.

Upcoming main Moon phases

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October after 28 days on 29 October 2012 at 19:50.

Apparent angular diameter ∠1789"

Lunar disc appears visually 6.91% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1917".

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 157 / 1110

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 157 of Meeus index or 1110 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.41 days

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

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 is ∠334.3°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon before apogee

12 days after point of perigee on 19 September 2012 at 02:52, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 3 days until it gets to the point of apogee on 5 October 2012 at 00:43.

Distance to Moon 400 629 km

Moon is 400 629 km (248 939 mi) away from Earth on this date. At previous perigee point before 12 days, distance is 365 749 km (227 266 mi). Moon moves farther next 3 days until apogee, when Earth-Moon distance reaches 405 162 km (251 756 mi).

Moon before descending node

10 days after its ascending node on 20 September 2012 at 12:54, the Moon follows the northern part of its orbit for the next 2 days untill it crosses the ecliptic from North to South in descending node on 4 October 2012 at 05:15.

Draconic month

10 days after its beginning, the Moon is moving from the beginning to the first part of current draconic month.

Previous | Current draconic month | Next

Moon before northern standstill

9 days after previous South standstill on 22 September 2012 at 00:11, when Moon reaches southern declination of ∠-21.135°, lunar orbit moves northward for the next 4 days to face North declination of ∠21.024° in the next northern standstill on 6 October 2012 at 01:40.

Syzygy in 14 days

After 14 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 15 October 2012 at 12:02.
