Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 150 / 1103

The Moon is 8 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 150 of Meeus index or 1103 from Brown series.

Synodic month length 29.67 days

Length of current 150 lunation is 29 days, 16 hours and 3 minutes. It is 38 minutes shorter than next lunation 151 length.

Lunation length longer than mean

Length of current synodic month is 3 hours and 18 minutes longer than the mean length of synodic month, but it is still 3 hours and 44 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠107.8°

This New Moon true anomaly is ∠107.8°. At beginning of next synodic month true anomaly will be ∠142.2°. 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 after apogee

2 days after point of apogee on 27 February 2012 at 14:01 in ♉ Taurus. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 10 March 2012 at 10:02 in ♎ Libra.

Distance to Moon 400 679 km

Moon is 400 679 km (248 970 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 362 401 km (225 186 mi).

Moon after descending node

1 day after its descending node on 29 February 2012 at 22:37 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 12 days, until it will cross the ecliptic from South to North in ascending node on 13 March 2012 at 20:41 in ♐ Sagittarius.

Moon in northern standstill

At 16:13 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠22.150°. Next 13 days the lunar orbit will move in opposite southward direction to face South declination of ∠-22.032° in its southern standstill point on 14 March 2012 at 14:09 in ♐ Sagittarius.
