Moon phase and lunation

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

4 days after Last Quarter

Previous main lunar phase is the Last Quarter before 4 days on 26 October 2013 at 23:41.

Beaver Moon after 17 days

Next Full Moon is the Beaver Moon of November after 17 days on 17 November 2013 at 15:16.

Moon in Virgo

Moon is leaving the last ∠1° of Virgo tropical zodiac sector and enters Libra later.

Upcoming Moon phases

Apparent angular diameter ∠1843"

Lunar disc appears visually 4.8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1843" and ∠1933".

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 170 / 1123

Moon is 26 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 170 of Meeus index or 1123 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.51 days

Length of current 170 lunation is 29 days, 12 hours and 15 minutes. It is 43 minutes longer than next lunation 171.

Lunation length shorter than mean

Length of current synodic month is 29 minutes shorter than the mean length of synodic month, but it is still 5 hours and 40 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠285.3°

This lunation true anomaly is ∠285.3°. At the beginning of next synodic month true anomaly is ∠315°. 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 perigee

5 days after point of apogee on 25 October 2013 at 14:25, lunar orbit gets closer while the Moon moves inward the Earth. It keeps this direction for next 5 days until it gets to the point of perigee on 6 November 2013 at 09:28.

Distance to Moon 389 012 km

Moon is 389 012 km (241 721 mi) away from Earth on this date. At previous apogee point before 5 days, distance is 404 561 km (251 383 mi). Moon moves closer next 5 days until perigee, when Earth-Moon distance reaches 365 362 km (227 025 mi).

Moon before ascending node

11 days after its descending node on 19 October 2013 at 21:47, the Moon follows the southern part of its orbit for the next 2 days untill it crosses the ecliptic from South to North in ascending node on 3 November 2013 at 06:52.

Draconic month

24 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon before southern standstill

8 days after previous North standstill on 23 October 2013 at 09:13, when Moon reaches northern declination of ∠19.509°, lunar orbit moves southward for the next 5 days to face South declination of ∠-19.511° in the next southern standstill on 6 November 2013 at 06:43.

Syzygy in 3 days

After 3 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 3 November 2013 at 12:50.
