Previous main lunar phase is the First Quarter before 4 days on 27 January 2015 at 04:48.
Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.
Moon is passing first ∠2° of ♋ Cancer tropical zodiac sector.
Lunar disc appears visually 6.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1825" and ∠1947".
Next Full Moon is the Snow Moon of February 2015 after 3 days on 3 February 2015 at 23:09.
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.
The Moon is 11 days young. Earth's natural satellite is moving from the first to the middle part of current synodic month. This is lunation 186 of Meeus index or 1139 from Brown series.
Length of current 186 lunation is 29 days, 10 hours and 34 minutes. It is 45 minutes longer than next lunation 187 length.
Length of current synodic month is 2 hours and 10 minutes shorter than the mean length of synodic month, but it is still 3 hours and 59 minutes longer, compared to 21st century shortest.
This lunation true anomaly is ∠338.3°. At the beginning of next synodic month true anomaly will be ∠354.5°. 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°).
9 days after point of perigee on 21 January 2015 at 20:06 in ♒ Aquarius. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 5 days, until it get to the point of next apogee on 6 February 2015 at 06:25 in ♍ Virgo.
Moon is 392 711 km (244 019 mi) away from Earth on this date. Moon moves farther next 5 days until apogee, when Earth-Moon distance will reach 406 155 km (252 373 mi).
6 days after its descending node on 25 January 2015 at 10:23 in ♈ Aries, the Moon is following the southern part of its orbit for the next 8 days, until it will cross the ecliptic from South to North in ascending node on 8 February 2015 at 17:10 in ♎ Libra.
18 days after beginning of current draconic month in ♎ Libra, the Moon is moving from the second to the final part of it.
At 00:59 on this date the Moon is meeting its North standstill point, when it will reach northern declination of ∠18.513°. Next 14 days the lunar orbit will move in opposite southward direction to face South declination of ∠-18.402° in its southern standstill point on 14 February 2015 at 17:17 in ♐ Sagittarius.
After 3 days on 3 February 2015 at 23:09 in ♌ Leo, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.
