The Moon is 22 days old. Earth's natural satellite is moving through the last part of current synodic month. This is lunation 16 of Meeus index or 969 from Brown series.

Synodic month length 29.47 days

The length of the lunation is 29 days, 11 hours and 20 minutes. It is 2 hours and 8 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 1 hour and 24 minutes shorter than the mean synodic month length. It is 4 hours and 45 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠267.3°

At the beginning of the lunation cycle the true anomaly is ∠267.3°. At the beginning of next synodic month the true anomaly is going to be ∠299.7°.

Moon at apogee

Moon is at apogee at 01:29. It is 12 days after previous perigee on 2 May 2001 at 03:37 in ♍ Virgo. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 11 days, until point of next perigee on 27 May 2001 at 07:07 in ♌ Leo.

Distance to Moon 404 141 km

This apogee Moon is 404 141 km (251 122 mi) away from Earth. This is the year's closest apogee of 2001. It is 1 267 km further than the mean apogee distance, but it is still 90 km closer than the farthest apogee of 21st century.

Moon after descending node

4 days after descending node on 11 May 2001 at 11:02 in ♑ Capricorn. The Moon is located south of the ecliptic over the following 10 days, until the lunar orbit crosses from South to North in ascending node on 25 May 2001 at 13:51 in ♊ Gemini.

Draconic month

17 days since the beginning of current draconic month in ♋ Cancer, the Moon is navigating from the second to the final part of the cycle.

Moon after southern standstill

3 days since the previous standstill on 11 May 2001 at 20:26 in ♑ Capricorn when the Moon has reached South declination of ∠-23.329°, the lunar orbit is extending northward over the next 10 days to face maximum declination of ∠23.388° at the point of next northern standstill on 25 May 2001 at 23:03 in ♋ Cancer.

Syzygy in 7 days

In 7 days on 23 May 2001 at 02:46 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.
