Moon phase and lunation details

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 12 March 2011 at 23:45.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Moon in ♍ Virgo

Moon is passing about ∠10° of ♍ Virgo tropical zodiac sector.

Apparent angular diameter ∠1967"

Lunar disc appears visually 2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1967" and ∠1928".

Worm Moon after 1 day

Next Full Moon is the Worm Moon of March 2011 after 1 day on 19 March 2011 at 18:10.

Upcoming main Moon phases

  • Full Moon in Virgo ♍ on 19 March 2011 at 18:10
  • Last Quarter in Capricorn ♑ on 26 March 2011 at 12:07
  • New Moon in Aries ♈ on 3 April 2011 at 14:32
  • First Quarter in Cancer ♋ on 11 April 2011 at 12:05

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 138 / 1091

The Moon is 13 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 138 of Meeus index or 1091 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.74 days

The length of the lunation is 29 days, 17 hours and 46 minutes. It is 1 hour and 28 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 5 hours and 2 minutes longer than the mean synodic month length. It is 2 hours and 1 minute shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠167°

At the beginning of the lunation cycle the true anomaly is ∠167°. At the beginning of next synodic month the true anomaly is going to be ∠190.9°.

Moon before apogee

12 days after point of apogee on 6 March 2011 at 07:50 in ♈ Aries. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next day, until the Moon reaches the point of next perigee on 19 March 2011 at 19:09 in ♍ Virgo.

Previous apogeeNext perigee

Distance to Moon 364 408 km

The Moon is 364 408 km (226 433 mi) away from Earth and getting closer over the next day until the point perigee when Earth-Moon distance is going to be 356 578 km (221 567 mi).

Moon after descending node

5 days after descending node on 13 March 2011 at 11:55 in ♊ Gemini. The Moon is located south of the ecliptic over the following 7 days, until the lunar orbit crosses from South to North in ascending node on 25 March 2011 at 21:09 in ♐ Sagittarius.

Previous nodeNext node

Draconic month

19 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.

Moon after northern standstill

5 days since the previous standstill on 12 March 2011 at 17:06 in ♊ Gemini when the Moon has reached North declination of ∠23.825°, the lunar orbit is extending southward over the next 6 days to face maximum declination of ∠-23.716° at the point of next southern standstill on 25 March 2011 at 05:02 in ♐ Sagittarius.

Syzygy in 1 day

In 1 day on 19 March 2011 at 18:10 in ♍ Virgo the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
