Previous date | Moon Today | Next date

5 days after Last Quarter

Previous main lunar phase is the Last Quarter before 5 days on 3 February 2013 at 13:56.

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.

Apparent angular diameter ∠1932"

Lunar disc appears visually 0.66% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1932" and ∠1944".

Snow Moon after 16 days

Next Full Moon is the Snow Moon of February after 16 days on 25 February 2013 at 20:26.

Moon in Aquarius

Moon is passing about ∠10° of Aquarius tropical zodiac sector.

Upcoming Moon phases

Lunar orbit details for

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 161 / 1114

Moon is 28 days old. Earth's natural satellite is moving from the second to the final part of current synodic month. This is lunation 161 of Meeus index or 1114 from Brown series.

Previous | Current lunation | Next

Synodic month length 29.48 days

Length of current 161 lunation is 29 days, 11 hours and 36 minutes. It is 55 minutes shorter than next lunation 162.

Lunation length shorter than mean

Length of current synodic month is 1 hour and 8 minutes shorter than the mean length of synodic month, but it is still 5 hours and 1 minute longer, compared to 21st century shortest.

True anomaly ∠23.3°

This lunation true anomaly is ∠23.3°. At the beginning of next synodic month true anomaly is ∠44.2°. 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

1 day after point of perigee on 7 February 2013 at 12:09, lunar orbit gets wider while the Moon moves outward the Earth. It keeps this direction for next 9 days until it gets to the point of apogee on 19 February 2013 at 06:30.

Distance to Moon 371 061 km

Moon is 371 061 km (230 567 mi) away from Earth on this date. At previous perigee point before 1 day, distance is 365 314 km (226 996 mi). Moon moves farther next 9 days until apogee, when Earth-Moon distance reaches 404 475 km (251 329 mi).

Moon after ascending node

5 days after its ascending node on 4 February 2013 at 02:14, the Moon follows the northern part of its orbit for the next 7 days untill it crosses the ecliptic from North to South in descending node on 17 February 2013 at 02:57.

Draconic month

5 days after its beginning, the Moon is moving from the beginning to the first part of current draconic month.

Previous | Current draconic month | Next

Moon after southern standstill

3 days after previous South standstill on 6 February 2013 at 00:27, when Moon reaches southern declination of ∠-20.704°, lunar orbit moves northward for the next 10 days to face North declination of ∠20.583° in the next northern standstill on 19 February 2013 at 13:35.

Syzygy in 1 day

After 1 day the Moon is in New Moon conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy on 10 February 2013 at 07:20.
