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 115 / 1068

The Moon is 21 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 115 of Meeus index or 1068 from Brown series.

Synodic month length 29.37 days

The length of the lunation is 29 days, 8 hours and 48 minutes. It is 1 hour and 24 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 shorter than mean

The length of the current synodic month is 3 hours and 56 minutes shorter than the mean synodic month length. It is 2 hours and 13 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠311.7°

At the beginning of the lunation cycle the true anomaly is ∠311.7°. At the beginning of next synodic month the true anomaly is going to be ∠332.7°.

Moon after apogee

2 days after point of apogee on 14 May 2009 at 02:57 in ♑ Capricorn. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 26 May 2009 at 03:44 in ♊ Gemini.

Distance to Moon 402 066 km

The Moon is 402 066 km (249 832 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 361 155 km (224 411 mi).

Moon after ascending node

1 day after ascending node on 15 May 2009 at 07:13 in ♒ Aquarius. The Moon is located north of the ecliptic over the following 11 days, until the lunar orbit crosses from North to South in descending node on 28 May 2009 at 10:19 in ♌ Leo.

Draconic month

1 day since the beginning of current draconic month in ♒ Aquarius, the Moon is navigating from the beginning to the first part of the cycle.

Moon after southern standstill

4 days since the previous standstill on 11 May 2009 at 20:03 in ♐ Sagittarius when the Moon has reached South declination of ∠-26.486°, the lunar orbit is extending northward over the next 9 days to face maximum declination of ∠26.451° at the point of next northern standstill on 25 May 2009 at 16:56 in ♊ Gemini.

Syzygy in 8 days

In 8 days on 24 May 2009 at 12:11 in ♊ Gemini the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
