Moon phase and lunation details
4 days after Full Moon
Previous main lunar phase is the Full Moon before 4 days on 13 August 2011 at 18:58.
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 passing about ∠18° of ♈ Aries tropical zodiac sector.
Apparent angular diameter ∠1768"
Lunar disc appears visually 7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1896".
Sturgeon Moon before 4 days
Next Full Moon is the Harvest Moon of September 2011 after 24 days on 12 September 2011 at 09:27.
Upcoming main Moon phases
- Last Quarter in Taurus ♉ on 21 August 2011 at 21:55
- New Moon in Virgo ♍ on 29 August 2011 at 03:04
- First Quarter in Sagittarius ♐ on 4 September 2011 at 17:39
- Full Moon in Pisces ♓ on 12 September 2011 at 09:27
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 143 / 1096
The Moon is 19 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 143 of Meeus index or 1096 from Brown series.
Synodic month length 29.35 days
The length of the lunation is 29 days, 8 hours and 24 minutes. It is 19 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 4 hours and 20 minutes shorter than the mean synodic month length. It is 1 hour and 49 minutes longer compared to 21st century's shortest synodic month length.
Lunar orbit position on
True anomaly ∠312.1°
At the beginning of the lunation cycle the true anomaly is ∠312.1°. At the beginning of next synodic month the true anomaly is going to be ∠333.4°.
Moon at apogee
Moon is at apogee at 16:23. It is 15 days after previous perigee on 2 August 2011 at 20:59 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 30 August 2011 at 17:35 in ♍ Virgo.
Distance to Moon 405 161 km
This apogee Moon is 405 161 km (251 755 mi) away from Earth. It is 247 km further than the mean apogee distance, but it is still 1 548 km closer than the farthest apogee of 21st century.
Moon before descending node
9 days after ascending node on 9 August 2011 at 06:35 in ♐ Sagittarius. The Moon is located north of the ecliptic over the following 5 days, until the lunar orbit crosses from North to South in descending node on 23 August 2011 at 17:23 in ♊ Gemini.
Draconic month
9 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
9 days since the previous standstill on 8 August 2011 at 23:15 in ♐ Sagittarius when the Moon has reached South declination of ∠-23.270°, the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠23.149° at the point of next northern standstill on 23 August 2011 at 12:17 in ♊ Gemini.
Syzygy in 10 days
In 10 days on 29 August 2011 at 03:04 in ♍ Virgo 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.
