Synodic month length 29.31 days

Length of current 118 lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 minutes shorter than next lunation 119 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 17 minutes shorter than the mean length of synodic month, but it is still 52 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠4.5°

This New Moon true anomaly is ∠4.5°. At beginning of next synodic month true anomaly will be ∠20.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon before perigee

11 days after point of apogee on 4 August 2009 at 00:42 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 3 days, until it get to the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.

Distance to Moon 367 607 km

Moon is 367 607 km (228 420 mi) away from Earth on this date. Moon moves closer next 3 days until perigee, when Earth-Moon distance will reach 359 642 km (223 471 mi).

Moon before descending node

10 days after its ascending node on 4 August 2009 at 21:42 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 18 August 2009 at 14:06 in ♋ Cancer.

Moon in northern standstill

At 21:54 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠26.442°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-26.391° in its southern standstill point on 28 August 2009 at 20:17 in ♐ Sagittarius.

Syzygy in 4 days

After 4 days on 20 August 2009 at 10:01 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
