Moon phase and lunation details

2 days after First Quarter

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 ♎ Libra

Moon is passing about ∠5° of ♎ Libra tropical zodiac sector.

Apparent angular diameter ∠1950"

Lunar disc appears visually 2.9% wider than solar disc. Moon and Sun apparent angular diameters are ∠1950" and ∠1895".

Flower Moon after 4 days

Next Full Moon is the Flower Moon of May 2010 after 4 days on 27 May 2010 at 23:07.

Synodic month length 29.42 days

The length of the lunation is 29 days, 10 hours and 10 minutes. It is 1 hour and 44 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 shorter than mean

The length of the current synodic month is 2 hours and 34 minutes shorter than the mean synodic month length. It is 3 hours and 35 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠282.4°

At the beginning of the lunation cycle the true anomaly is ∠282.4°. At the beginning of next synodic month the true anomaly is going to be ∠311.3°.

Moon after perigee

3 days after point of perigee on 20 May 2010 at 08:38 in ♌ Leo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 11 days, until the Moon reaches the point of next apogee on 3 June 2010 at 16:50 in ♒ Aquarius.

Previous perigeeNext apogee

Distance to Moon 367 642 km

The Moon is 367 642 km (228 442 mi) away from Earth and getting further over the next 11 days until the point apogee when Earth-Moon distance is going to be 404 266 km (251 199 mi).

Moon after descending node

5 days after descending node on 17 May 2010 at 15:39 in ♋ Cancer. 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 30 May 2010 at 18:07 in ♑ Capricorn.

Draconic month

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

Moon before southern standstill

7 days since the previous standstill on 15 May 2010 at 23:07 in ♊ Gemini when the Moon has reached North declination of ∠25.049°, the lunar orbit is extending southward over the next 5 days to face maximum declination of ∠-25.029° at the point of next southern standstill on 28 May 2010 at 22:09 in ♐ Sagittarius.

Syzygy in 4 days

In 4 days on 27 May 2010 at 23:07 in ♏ Scorpio 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.
