Moon phase and lunation details
3 days after Full Moon
Previous main lunar phase is the Full Moon before 3 days on 12 September 2011 at 09:27.
Moonrise and moonset
Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.
Moon in ♈ Aries
Moon is leaving the last ∠4° of ♈ Aries tropical zodiac sector and will enter ♉ Taurus later.
Apparent angular diameter ∠1768"
Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1908".
Harvest Moon before 3 days
Next Full Moon is the Hunter Moon of October 2011 after 26 days on 12 October 2011 at 02:06.
Upcoming main Moon phases
- Last Quarter in Gemini ♊ on 20 September 2011 at 13:39
- New Moon in Libra ♎ on 27 September 2011 at 11:09
- First Quarter in Capricorn ♑ on 4 October 2011 at 03:15
- Full Moon in Aries ♈ on 12 October 2011 at 02:06
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 144 / 1097
The Moon is 17 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 144 of Meeus index or 1097 from Brown series.
Synodic month length 29.34 days
The length of the lunation is 29 days, 8 hours and 5 minutes. This is the year's shortest synodic month of 2011. It is 42 minutes shorter 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 4 hours and 39 minutes shorter than the mean synodic month length. It is 1 hour and 30 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠333.4°
At the beginning of the lunation cycle the true anomaly is ∠333.4°. At the beginning of next synodic month the true anomaly is going to be ∠350.1°.
Moon at apogee
Moon is at apogee at 06:23. It is 15 days after previous perigee on 30 August 2011 at 17:35 in ♍ Virgo. Lunar orbit is going to narrow while the Moon is moving towards the Earth over the next 12 days, until point of next perigee on 28 September 2011 at 01:01 in ♎ Libra.
Distance to Moon 406 068 km
This apogee Moon is 406 068 km (252 319 mi) away from Earth. It is 660 km further than the mean apogee distance, but it is still 641 km closer than the farthest apogee of 21st century.
Moon before descending node
10 days after ascending node on 5 September 2011 at 07:36 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 4 days, until the lunar orbit crosses from North to South in descending node on 19 September 2011 at 19:38 in ♊ Gemini.
Draconic month
10 days since the beginning of current draconic month in ♐ Sagittarius, the Moon is navigating from the beginning to the first part of the cycle.
Moon before northern standstill
10 days since the previous standstill on 5 September 2011 at 05:01 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.047°, the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠22.890° at the point of next northern standstill on 19 September 2011 at 20:05 in ♊ Gemini.
Syzygy in 11 days
In 11 days on 27 September 2011 at 11:09 in ♎ Libra 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.
