Neap tide
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunation 139 / 1092
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 139 of Meeus index or 1092 from Brown series.
Synodic month length 29.68 days
Length of current 139 lunation is 29 days, 16 hours and 18 minutes. It is 2 hours and 6 minutes longer than next lunation 140 length.
Lunation length longer than mean
Length of current synodic month is 3 hours and 34 minutes longer than the mean length of synodic month, but it is still 3 hours and 29 minutes shorter, compared to 21st century longest.
Lunar orbit position on
True anomaly ∠190.9°
This lunation true anomaly is ∠190.9°. At the beginning of next synodic month true anomaly will be ∠216.7°. 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
9 days after point of apogee on 2 April 2011 at 09:00 in ♓ Pisces. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 17 April 2011 at 05:59 in ♎ Libra.
Distance to Moon 376 482 km
Moon is 376 482 km (233 935 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 358 088 km (222 506 mi).
Moon after descending node
1 day after its descending node on 9 April 2011 at 12:48 in ♊ Gemini, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 22 April 2011 at 01:05 in ♐ Sagittarius.
Draconic month
16 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
Moon after northern standstill
2 days after previous North standstill on 8 April 2011 at 22:55 in ♊ Gemini, when Moon has reached northern declination of ∠23.569°. Next 10 days the lunar orbit moves southward to face South declination of ∠-23.498° in the next southern standstill on 21 April 2011 at 13:40 in ♐ Sagittarius.
Syzygy in 6 days
After 6 days on 18 April 2011 at 02:44 in ♎ Libra, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
