Moon phase and lunation details

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.

5 days after Full Moon

Previous main lunar phase is the Full Moon before 5 days on 29 August 2015 at 18:35.

Moon in ♉ Taurus

Moon is leaving the last ∠1° of ♉ Taurus tropical zodiac sector and will enter ♊ Gemini later.

Upcoming main Moon phases

Sturgeon Moon before 5 days

Next Full Moon is the Harvest Moon of September after 23 days on 28 September 2015 at 02:50.

Apparent angular diameter ∠1925"

Lunar disc appears visually 1.16% wider than solar disc. Moon and Sun apparent angular diameters are ∠1925" and ∠1903".

Neap tide

There is low ocean tide today. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Lunation 193 / 1146

Moon is 21 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 193 of Meeus index or 1146 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.66 days

Length of current 193 lunation is 29 days, 15 hours and 48 minutes. It is 1 hour and 36 minutes shorter than next lunation 194.

Lunation length longer than mean

Length of current synodic month is 3 hours and 4 minutes longer than the mean length of synodic month, but it is still 3 hours and 59 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠144.1°

This lunation true anomaly is ∠144.1°. At the beginning of next synodic month true anomaly is ∠169.3°. The length of upcoming synodic months increases since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after perigee

4 days after point of perigee on 30 August 2015 at 15:24, 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 14 September 2015 at 11:28.

Distance to Moon 372 379 km

Moon is 372 379 km (231 386 mi) away from Earth on this date. At previous perigee point before 4 days, distance is 358 289 km (222 630 mi). Moon moves farther next 10 days until apogee, when Earth-Moon distance reaches 406 466 km (252 566 mi).

Moon after descending node

4 days after its descending node on 31 August 2015 at 10:16, the Moon follows the southern part of its orbit for the next 9 days untill it crosses the ecliptic from South to North in ascending node on 14 September 2015 at 04:38.

Draconic month

17 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 before northern standstill

10 days after previous South standstill on 25 August 2015 at 03:44, when Moon reaches southern declination of ∠-18.206°, lunar orbit moves northward for the next 2 days to face North declination of ∠18.163° in the next northern standstill on 6 September 2015 at 17:06.

Syzygy in 8 days

After 8 days the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 13 September 2015 at 06:41.
