Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 30 January 2010 at 06:18.

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 ♌ Leo

Moon is leaving the last ∠1° of ♌ Leo tropical zodiac sector and will enter ♍ Virgo later.

Apparent angular diameter ∠1970"

Lunar disc appears visually 1.1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1970" and ∠1947".

Wolf Moon before 1 day

Next Full Moon is the Snow Moon of February 2010 after 28 days on 28 February 2010 at 16:38.

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 124 / 1077

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 124 of Meeus index or 1077 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.82 days

Length of current 124 lunation is 29 days, 19 hours and 40 minutes. This is the year's longest synodic month of 2010. It is 1 hour and 30 minutes longer than next lunation 125 length.

Lunation length longer than mean

Length of current synodic month is 6 hours and 56 minutes longer than the mean length of synodic month, but it is still 7 minutes shorter, compared to 21st century longest.

Lunar orbit position on

True anomaly ∠164.3°

This lunation true anomaly is ∠164.3°. At the beginning of next synodic month true anomaly will be ∠188.9°. The length of upcoming synodic months will keep decreasing since the true anomaly gets closer to the value of New Moon at point of perigee (∠0° or ∠360°).

Moon after perigee

1 day after point of perigee on 30 January 2010 at 09:03 in ♌ Leo. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 12 days, until it get to the point of next apogee on 13 February 2010 at 02:06 in ♒ Aquarius.

Previous perigeeNext apogee

Distance to Moon 363 935 km

Moon is 363 935 km (226 139 mi) away from Earth on this date. Moon moves farther next 12 days until apogee, when Earth-Moon distance will reach 406 542 km (252 613 mi).

Moon after descending node

2 days after its descending node on 29 January 2010 at 00:02 in ♋ Cancer, the Moon is following the southern part of its orbit for the next 10 days, until it will cross the ecliptic from South to North in ascending node on 11 February 2010 at 04:58 in ♑ Capricorn.

Draconic month

16 days after beginning of current draconic month in ♑ Capricorn, the Moon is moving from the second to the final part of it.

Moon after northern standstill

4 days after previous North standstill on 26 January 2010 at 21:04 in ♊ Gemini, when Moon has reached northern declination of ∠25.783°. Next 8 days the lunar orbit moves southward to face South declination of ∠-25.749° in the next southern standstill on 8 February 2010 at 14:27 in ♐ Sagittarius.

Syzygy in 13 days

After 13 days on 14 February 2010 at 02:51 in ♒ Aquarius, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
