Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 12 October 2011 at 02:06.

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 ♉ Taurus

Moon is passing about ∠5° of ♉ Taurus tropical zodiac sector.

Apparent angular diameter ∠1770"

Lunar disc appears visually 8.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1770" and ∠1923".

Hunter Moon before 1 day

Next Full Moon is the Beaver Moon of November 2011 after 28 days on 10 November 2011 at 20:16.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 145 / 1098

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 145 of Meeus index or 1098 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.37 days

Length of current 145 lunation is 29 days, 8 hours and 47 minutes. It is 1 hour and 27 minutes shorter than next lunation 146 length.

Lunation length shorter than mean

Length of current synodic month is 3 hours and 57 minutes shorter than the mean length of synodic month, but it is still 2 hours and 12 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠350.1°

This New Moon true anomaly is ∠350.1°. At beginning of next synodic month true anomaly will be ∠5.3°. 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

1 day after point of apogee on 12 October 2011 at 11:43 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 13 days, until it get to the point of next perigee on 26 October 2011 at 12:26 in ♎ Libra.

Previous apogeeNext perigee

Distance to Moon 404 969 km

Moon is 404 969 km (251 636 mi) away from Earth on this date. Moon moves closer next 13 days until perigee, when Earth-Moon distance will reach 357 051 km (221 861 mi).

Moon before descending node

11 days after its ascending node on 2 October 2011 at 09:09 in ♐ Sagittarius, the Moon is following the northern part of its orbit for the next 3 days, until it will cross the ecliptic from North to South in descending node on 16 October 2011 at 21:01 in ♊ Gemini.

Draconic month

11 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the beginning to the first part of it.

Moon before northern standstill

11 days after previous South standstill on 2 October 2011 at 11:38 in ♐ Sagittarius, when Moon has reached southern declination of ∠-22.791°. Next 3 days the lunar orbit moves northward to face North declination of ∠22.665° in the next northern standstill on 17 October 2011 at 02:06 in ♊ Gemini.

Syzygy in 13 days

After 13 days on 26 October 2011 at 19:56 in ♎ Libra, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
