Spring tide

There is high Full Moon ocean tide on this date. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Earth-Moon syzygy alignment.

Lunation 140 / 1093

The Moon is 15 days old. Earth's natural satellite is moving through the middle part of current synodic month. This is lunation 140 of Meeus index or 1093 from Brown series.

Synodic month length 29.59 days

The length of the lunation is 29 days, 14 hours and 12 minutes. It is 2 hours and 21 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length longer than mean

The length of the current synodic month is 1 hour and 28 minutes longer than the mean synodic month length. It is 5 hours and 35 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit position on

True anomaly ∠216.7°

At the beginning of the lunation cycle the true anomaly is ∠216.7°. At the beginning of next synodic month the true anomaly is going to be ∠248.4°.

Moon after perigee

2 days after point of perigee on 15 May 2011 at 11:18 in ♎ Libra. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next apogee on 27 May 2011 at 09:58 in ♈ Aries.

Distance to Moon 370 177 km

The Moon is 370 177 km (230 017 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 405 006 km (251 659 mi).

Moon before ascending node

10 days after descending node on 6 May 2011 at 14:54 in ♊ Gemini. The Moon is located south of the ecliptic over the following day, until the lunar orbit crosses from South to North in ascending node on 19 May 2011 at 09:03 in ♐ Sagittarius.

Draconic month

25 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the second to the final part of the cycle.

Moon before southern standstill

11 days since the previous standstill on 6 May 2011 at 03:54 in ♊ Gemini when the Moon has reached North declination of ∠23.421°, the lunar orbit is extending southward over the next day to face maximum declination of ∠-23.403° at the point of next southern standstill on 18 May 2011 at 23:26 in ♐ Sagittarius.

Sun-Earth-Moon syzygy

The Moon is in a Full Moon geocentric opposition with the Sun and thus forming Sun-Earth-Moon syzygy alignment.
