Moon phase and lunation details

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

2 days after First Quarter

Previous main lunar phase is the First Quarter before 2 days on 6 August 2011 at 11:08.

Moon in ♐ Sagittarius

Moon is passing about ∠12° of ♐ Sagittarius tropical zodiac sector.

Upcoming main Moon phases

Sturgeon Moon after 5 days

Next Full Moon is the Sturgeon Moon of August after 5 days on 13 August 2011 at 18:58.

Apparent angular diameter ∠1927"

Lunar disc appears visually 1.79% wider than solar disc. Moon and Sun apparent angular diameters are ∠1927" and ∠1892".

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

Moon is 9 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 143 of Meeus index or 1096 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.35 days

Length of current 143 lunation is 29 days, 8 hours and 24 minutes. It is 19 minutes longer than next lunation 144.

Lunation length shorter than mean

Length of current synodic month is 4 hours and 20 minutes shorter than the mean length of synodic month, but it is still 1 hour and 49 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠312.1°

This lunation true anomaly is ∠312.1°. At the beginning of next synodic month true anomaly is ∠333.4°. The length of upcoming synodic months decreases since the true anomaly gets closer to the value of New Moon at point of perigee (∠0°or∠360°).

Moon after perigee

5 days after point of perigee on 2 August 2011 at 20:59, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 10 days until it gets to the point of apogee on 18 August 2011 at 16:23.

Distance to Moon 372 055 km

Moon is 372 055 km (231 184 mi) away from Earth on this date. At previous perigee point before 5 days, distance is 365 756 km (227 270 mi). Moon moves farther next 10 days until apogee, when Earth-Moon distance reaches 405 161 km (251 755 mi).

Moon before ascending node

11 days after its descending node on 27 July 2011 at 12:03, the Moon follows the southern part of its orbit for the next 1 day untill it crosses the ecliptic from South to North in ascending node on 9 August 2011 at 06:35.

Draconic month

26 days after its beginning, the Moon is moving from the second to the final part of current draconic month.

Previous | Current draconic month | Next

Moon in southern standstill

At 23:15 on this date Moon meets its South standstill point and reaches southern declination of ∠-23.270°. Next 15 days lunar orbit moves northward in opposite direction to face North declination of ∠23.149° in its northern standstill point on 23 August 2011 at 12:17.

Syzygy in 5 days

After 5 days the Moon is in Full Moon opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy on 13 August 2011 at 18:58.
