Synodic month length 29.65 days

Length of current 70 lunation is 29 days, 15 hours and 42 minutes. This is the year's longest synodic month of 2005. It is 45 minutes longer than next lunation 71 length.

Lunation length longer than mean

Length of current synodic month is 2 hours and 58 minutes longer than the mean length of synodic month, but it is still 4 hours and 5 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠205.9°

This lunation true anomaly is ∠205.9°. At the beginning of next synodic month true anomaly will be ∠236.1°. 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 perigee

11 days after point of apogee on 1 September 2005 at 02:35 in ♌ Leo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 16 September 2005 at 13:58 in ♒ Aquarius.

Distance to Moon 368 067 km

Moon is 368 067 km (228 706 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 360 406 km (223 946 mi).

Moon in southern standstill

At 10:54 on this date the Moon is meeting its South standstill point, when it will reach southern declination of ∠-28.556°. Next 12 days the lunar orbit will move in opposite northward direction to face North declination of ∠28.594° in its northern standstill point on 25 September 2005 at 06:42 in ♋ Cancer.
