The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 141 of Meeus index or 1094 from Brown series.

Synodic month length 29.49 days

Length of current 141 lunation is 29 days, 11 hours and 51 minutes. It is 2 hours and 5 minutes longer than next lunation 142 length.

Lunation length shorter than mean

Length of current synodic month is 53 minutes shorter than the mean length of synodic month, but it is still 5 hours and 16 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠248.4°

This lunation true anomaly is ∠248.4°. At the beginning of next synodic month true anomaly will be ∠283.1°. 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 12 June 2011 at 01:42 in ♏ Scorpio. 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 24 June 2011 at 04:13 in ♈ Aries.

Distance to Moon 405 243 km

Moon is 405 243 km (251 806 mi) away from Earth on this date. Moon moves farther next day until apogee, when Earth-Moon distance will reach 404 275 km (251 205 mi).

Moon before descending node

7 days after its ascending node on 15 June 2011 at 18:35 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 30 June 2011 at 04:14 in ♊ Gemini.

Moon before northern standstill

8 days after previous South standstill on 15 June 2011 at 08:52 in ♐ Sagittarius, when Moon has reached southern declination of ∠-23.399°. Next 6 days the lunar orbit moves northward to face North declination of ∠23.399° in the next northern standstill on 29 June 2011 at 17:46 in ♊ Gemini.

Syzygy in 7 days

After 7 days on 1 July 2011 at 08:54 in ♋ Cancer, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
