Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 10 May 2017 at 21:43.

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 ♐ Sagittarius

Moon is passing about ∠9° of ♐ Sagittarius tropical zodiac sector.

Apparent angular diameter ∠1768"

Lunar disc appears visually 7.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1899".

Flower Moon before 1 day

Next Full Moon is the Strawberry Moon of June 2017 after 28 days on 9 June 2017 at 13:10.

Upcoming main Moon phases

  • Last Quarter in Pisces ♓ on 19 May 2017 at 00:33
  • New Moon in Taurus ♉ on 25 May 2017 at 19:44
  • First Quarter in Virgo ♍ on 1 June 2017 at 12:42
  • Full Moon in Sagittarius ♐ on 9 June 2017 at 13:10

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 214 / 1167

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 214 of Meeus index or 1167 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.31 days

Length of current 214 lunation is 29 days, 7 hours and 28 minutes. It is 42 minutes longer than next lunation 215 length.

Lunation length shorter than mean

Length of current synodic month is 5 hours and 16 minutes shorter than the mean length of synodic month, but it is still 53 minutes longer, compared to 21st century shortest.

Lunar orbit position on

True anomaly ∠340.4°

This lunation true anomaly is ∠340.4°. At the beginning of next synodic month true anomaly will be ∠356°. 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 in apogee

Moon is reaching point of apogee on this date at 19:51, this is 15 days after last perigee on 27 April 2017 at 16:18 in ♉ Taurus. Lunar orbit is starting to get closer, while the Moon is moving inward the Earth for 13 days ahead, until it will get to the point of next perigee on 26 May 2017 at 01:23 in ♊ Gemini.

Distance to Moon 406 212 km

This apogee Moon is 406 212 km (252 408 mi) away from Earth. It is 804 km farther than the mean apogee distance, but it is still 497 km closer than the farthest apogee of 21st century.

Moon before descending node

8 days after its ascending node on 4 May 2017 at 10:42 in ♍ Virgo, the Moon is following the northern part of its orbit for the next 6 days, until it will cross the ecliptic from North to South in descending node on 19 May 2017 at 01:30 in ♒ Aquarius.

Draconic month

8 days after beginning of current draconic month in ♍ Virgo, the Moon is moving from the beginning to the first part of it.

Moon before southern standstill

11 days after previous North standstill on 30 April 2017 at 13:33 in ♊ Gemini, when Moon has reached northern declination of ∠19.187°. Next 2 days the lunar orbit moves southward to face South declination of ∠-19.302° in the next southern standstill on 14 May 2017 at 20:29 in ♑ Capricorn.

Syzygy in 13 days

After 13 days on 25 May 2017 at 19:44 in ♉ Taurus, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
