Moon phase and lunation

Moonrise and moonset

Moon rises at sunset and sets at sunrise. It is visible all night and it is high in the sky around midnight.

It is Harvest Moon

The Full Moon on this date is the Harvest Moon of September.

Moon in Pisces

Moon is leaving the last ∠3° of Pisces tropical zodiac sector and enters Aries later.

Upcoming Moon phases

Apparent angular diameter ∠1896"

Lunar disc appears visually 0.79% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1896" and ∠1911".

Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Lunation 169 / 1122

Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 169 of Meeus index or 1122 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.54 days

Length of current 169 lunation is 29 days, 12 hours and 58 minutes. It is 43 minutes longer than next lunation 170.

Lunation length longer than mean

Length of current synodic month is 14 minutes longer than the mean length of synodic month, but it is still 6 hours and 49 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠249.2°

This lunation true anomaly is ∠249.2°. At the beginning of next synodic month true anomaly is ∠285.3°. 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 after perigee

3 days after point of perigee on 15 September 2013 at 16:34, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 8 days until it gets to the point of apogee on 27 September 2013 at 18:17.

Distance to Moon 378 136 km

Moon is 378 136 km (234 963 mi) away from Earth on this date. At previous perigee point before 3 days, distance is 367 388 km (228 284 mi). Moon moves farther next 8 days until apogee, when Earth-Moon distance reaches 404 309 km (251 226 mi).

Moon before descending node

9 days after its ascending node on 9 September 2013 at 17:29, the Moon follows the northern part of its orbit for the next 3 days untill it crosses the ecliptic from North to South in descending node on 22 September 2013 at 13:48.

Draconic month

9 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

6 days after previous South standstill on 12 September 2013 at 18:30, when Moon reaches southern declination of ∠-19.685°, lunar orbit moves northward for the next 6 days to face North declination of ∠19.599° in the next northern standstill on 26 September 2013 at 01:03.

Sun-Earth-Moon syzygy

The Moon is in Full Moon opposition with the Sun on this date and this alignment forms Sun-Earth-Moon syzygy.
