Synodic month length 29.48 days

Length of current 185 lunation is 29 days, 11 hours and 38 minutes. It is 1 hour and 4 minutes longer than next lunation 186 length.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 6 minutes shorter than the mean length of synodic month, but it is still 5 hours and 3 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠318°

This lunation true anomaly is ∠318°. At the beginning of next synodic month true anomaly will be ∠338.3°. 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 after apogee

2 days after point of apogee on 9 January 2015 at 18:17 in ♍ Virgo. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 9 days, until it get to the point of next perigee on 21 January 2015 at 20:06 in ♒ Aquarius.

Distance to Moon 400 918 km

Moon is 400 918 km (249 119 mi) away from Earth on this date. Moon moves closer next 9 days until perigee, when Earth-Moon distance will reach 359 643 km (223 472 mi).

New draconic month

At 15:33 on this date the Moon is completing its previous draconic month and is entering the new one.


Moon before southern standstill

8 days after previous North standstill on 3 January 2015 at 17:53 in ♊ Gemini, when Moon has reached northern declination of ∠18.650°. Next 5 days the lunar orbit moves southward to face South declination of ∠-18.577° in the next southern standstill on 18 January 2015 at 06:17 in ♐ Sagittarius.
