Quarter ♑ Capricorn
First Quarter is the lunar phase on . Seen from Earth, illuminated fraction of the Moon surface is 45% and growing larger. The 7 days young Moon is in ♑ Capricorn.
* The exact date and time of this First Quarter phase is on 11 October 2013 at 23:02 UTC.
Moon rises in the morning and sets in the evening. It is visible toward the southwest in early evening.
Moon is passing about ∠12° of ♑ Capricorn tropical zodiac sector.
Lunar disc appears visually 2.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1973" and ∠1923".
Next Full Moon is the Hunter Moon of October 2013 after 7 days on 18 October 2013 at 23:38.
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.
The Moon is 7 days young. Earth's natural satellite is moving through the first part of current synodic month. This is lunation 170 of Meeus index or 1123 from Brown series.
The length of the lunation is 29 days, 12 hours and 15 minutes. It is 43 minutes longer than the next lunation's length. The lengths of the following synodic months are going to decreasing with the true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).
The length of the current synodic month is 29 minutes shorter than the mean synodic month length. It is 5 hours and 40 minutes longer compared to 21st century's shortest synodic month length.
At the beginning of the lunation cycle the true anomaly is ∠285.3°. At the beginning of next synodic month the true anomaly is going to be ∠315°.
1 day after point of perigee on 10 October 2013 at 23:06 in ♐ Sagittarius. The lunar orbit is getting widen, while the Moon is moving away from the Earth. It will keep this direction over the next 14 days, until the Moon reaches the point of next apogee on 25 October 2013 at 14:25 in ♋ Cancer.
The Moon is 363 303 km (225 746 mi) away from Earth and getting further over the next 14 days until the point apogee when Earth-Moon distance is going to be 404 561 km (251 383 mi).
4 days after ascending node on 6 October 2013 at 22:08 in ♏ Scorpio. The Moon is located north of the ecliptic over the following 8 days, until the lunar orbit crosses from North to South in descending node on 19 October 2013 at 21:47 in ♉ Taurus.
4 days since the beginning of current draconic month in ♏ Scorpio, the Moon is navigating from the beginning to the first part of the cycle.
1 day since the previous standstill on 9 October 2013 at 23:52 in ♐ Sagittarius when the Moon has reached South declination of ∠-19.537°, the lunar orbit is extending northward over the next 11 days to face maximum declination of ∠19.509° at the point of next northern standstill on 23 October 2013 at 09:13 in ♊ Gemini.
In 7 days on 18 October 2013 at 23:38 in ♈ Aries the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
