Moon phase and lunation details

3 days after Last Quarter

Previous main lunar phase is the Last Quarter before 3 days on 18 January 2009 at 02:46.

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.

Moon in ♐ Sagittarius

Moon is passing about ∠9° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1775"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1950".

Snow Moon after 19 days

Next Full Moon is the Snow Moon of February 2009 after 19 days on 9 February 2009 at 14:49.

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 111 / 1064

The Moon is 25 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 111 of Meeus index or 1064 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.81 days

Length of current 111 lunation is 29 days, 19 hours and 33 minutes. This is the year's longest synodic month of 2009. It is 1 hour and 53 minutes longer than next lunation 112 length.

Lunation length longer than mean

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

Lunar orbit position on

True anomaly ∠186.6°

This lunation true anomaly is ∠186.6°. At the beginning of next synodic month true anomaly will be ∠213.2°. 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

11 days after point of perigee on 10 January 2009 at 10:52 in ♋ Cancer. 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 23 January 2009 at 00:11 in ♑ Capricorn.

Previous perigeeNext apogee

Distance to Moon 403 751 km

Moon is 403 751 km (250 879 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 406 116 km (252 349 mi).

Moon before ascending node

9 days after its descending node on 12 January 2009 at 08:34 in ♌ Leo, the Moon is following the southern part of its orbit for the next 5 days, until it will cross the ecliptic from South to North in ascending node on 26 January 2009 at 13:27 in ♒ Aquarius.

Draconic month

22 days after beginning of current draconic month in ♒ Aquarius, the Moon is moving from the second to the final part of it.

Moon before southern standstill

12 days after previous North standstill on 9 January 2009 at 05:38 in ♊ Gemini, when Moon has reached northern declination of ∠27.060°. Next day the lunar orbit moves southward to face South declination of ∠-27.081° in the next southern standstill on 22 January 2009 at 14:02 in ♐ Sagittarius.

Syzygy in 4 days

After 4 days on 26 January 2009 at 07:55 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
