Moon phase and lunation details

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 6 August 2009 at 00:55.

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.

Lunation 118 / 1071

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 118 of Meeus index or 1071 from Brown series.

Synodic month length 29.31 days

Length of current 118 lunation is 29 days, 7 hours and 27 minutes. It is 1 hour and 16 minutes shorter than next lunation 119 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 17 minutes shorter than the mean length of synodic month, but it is still 52 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠4.5°

This New Moon true anomaly is ∠4.5°. At beginning of next synodic month true anomaly will be ∠20.3°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after apogee

6 days after point of apogee on 4 August 2009 at 00:42 in ♑ Capricorn. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 8 days, until it get to the point of next perigee on 19 August 2009 at 04:53 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 389 321 km

Moon is 389 321 km (241 913 mi) away from Earth on this date. Moon moves closer next 8 days until perigee, when Earth-Moon distance will reach 359 642 km (223 471 mi).

Moon after ascending node

5 days after its ascending node on 4 August 2009 at 21:42 in ♑ Capricorn, the Moon is following the northern part of its orbit for the next 8 days, until it will cross the ecliptic from North to South in descending node on 18 August 2009 at 14:06 in ♋ Cancer.

Moon before northern standstill

8 days after previous South standstill on 1 August 2009 at 13:28 in ♐ Sagittarius, when Moon has reached southern declination of ∠-26.478°. Next 5 days the lunar orbit moves northward to face North declination of ∠26.442° in the next northern standstill on 15 August 2009 at 21:54 in ♊ Gemini.

Syzygy in 9 days

After 9 days on 20 August 2009 at 10:01 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
