The Moon is 9 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 142 of Meeus index or 1095 from Brown series.

Synodic month length 29.41 days

The length of the lunation is 29 days, 9 hours and 46 minutes. It is 1 hour and 22 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 58 minutes shorter than the mean synodic month length. It is 3 hours and 11 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠283.1°

At the beginning of the lunation cycle the true anomaly is ∠283.1°. At the beginning of next synodic month the true anomaly is going to be ∠312.1°.

Moon after perigee

1 day after point of perigee on 7 July 2011 at 14:04 in ♍ Virgo. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 12 days, until the Moon reaches the point of next apogee on 21 July 2011 at 22:46 in ♈ Aries.

Distance to Moon 364 592 km

The Moon is 364 592 km (226 547 mi) away from Earth and getting further over the next 12 days until the point apogee when Earth-Moon distance is going to be 404 358 km (251 256 mi).

Moon before ascending node

9 days after descending node on 30 June 2011 at 04:14 in ♊ Gemini. The Moon is located south of the ecliptic over the following 3 days, until the lunar orbit crosses from South to North in ascending node on 13 July 2011 at 02:27 in ♐ Sagittarius.

Draconic month

23 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 before southern standstill

9 days since the previous standstill on 29 June 2011 at 17:46 in ♊ Gemini when the Moon has reached North declination of ∠23.399°, the lunar orbit is extending southward over the next 3 days to face maximum declination of ∠-23.383° at the point of next southern standstill on 12 July 2011 at 16:51 in ♐ Sagittarius.

Syzygy in 5 days

In 5 days on 15 July 2011 at 06:40 in ♑ Capricorn 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.
