Moon phase and lunation details

1 day after Last Quarter

Previous main lunar phase is the Last Quarter before 1 day on 12 August 2001 at 07:53.

Moonrise and moonset

Moon rises after midnight to early morning and sets in the afternoon. It is visible in the early morning low to the east.

Moon in ♊ Gemini

Moon is passing about ∠5° of ♊ Gemini tropical zodiac sector.

Apparent angular diameter ∠1882"

Lunar disc appears visually 0.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1882" and ∠1894".

Harvest Moon after 20 days

Next Full Moon is the Harvest Moon of September 2001 after 20 days on 2 September 2001 at 21:43.

Upcoming main Moon phases

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 19 / 972

The Moon is 23 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 19 of Meeus index or 972 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.3 days

Length of current 19 lunation is 29 days, 7 hours and 11 minutes. This is the year's shortest synodic month of 2001. It is 21 minutes shorter than next lunation 20 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 33 minutes shorter than the mean length of synodic month, but it is still 36 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠342.5°

This lunation true anomaly is ∠342.5°. At the beginning of next synodic month true anomaly will be ∠358.1°. 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 before perigee

7 days after point of apogee on 5 August 2001 at 21:05 in ♒ Aquarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 5 days, until it get to the point of next perigee on 19 August 2001 at 05:43 in ♌ Leo.

Previous apogeeNext perigee

Distance to Moon 380 906 km

Moon is 380 906 km (236 684 mi) away from Earth on this date. Moon moves closer next 5 days until perigee, when Earth-Moon distance will reach 357 159 km (221 928 mi).

Moon before ascending node

12 days after its descending node on 1 August 2001 at 06:21 in ♑ Capricorn, the Moon is following the southern part of its orbit for the next 2 days, until it will cross the ecliptic from South to North in ascending node on 15 August 2001 at 17:05 in ♊ Gemini.

Draconic month

25 days after beginning of current draconic month in ♋ Cancer, the Moon is moving from the second to the final part of it.

Moon before northern standstill

11 days after previous South standstill on 1 August 2001 at 18:05 in ♑ Capricorn, when Moon has reached southern declination of ∠-23.427°. Next 2 days the lunar orbit moves northward to face North declination of ∠23.488° in the next northern standstill on 16 August 2001 at 03:52 in ♋ Cancer.

Syzygy in 5 days

After 5 days on 19 August 2001 at 02:55 in ♌ Leo, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
