Previous main lunar phase is the Full Moon before 1 day on 18 February 2011 at 08:36.
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 is passing about ∠17° of ♍ Virgo tropical zodiac sector.
Lunar disc appears visually 1.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1971" and ∠1941".
Next Full Moon is the Worm Moon of March 2011 after 28 days on 19 March 2011 at 18:10.
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 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 137 of Meeus index or 1090 from Brown series.
Length of current 137 lunation is 29 days, 18 hours and 15 minutes. This is the year's longest synodic month of 2011. It is 29 minutes longer than next lunation 138 length.
Length of current synodic month is 5 hours and 31 minutes longer than the mean length of synodic month, but it is still 1 hour and 32 minutes shorter, compared to 21st century longest.
This New Moon true anomaly is ∠139.2°. At beginning of next synodic month true anomaly will be ∠167°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).
Moon is reaching point of perigee on this date at 07:27, this is 12 days after last apogee on 6 February 2011 at 23:13 in ♓ Pisces. Lunar orbit is starting to get wider, while the Moon is moving outward the Earth for 14 days ahead, until it will get to the point of next apogee on 6 March 2011 at 07:50 in ♈ Aries.
This perigee Moon is 358 247 km (222 604 mi) away from Earth. It is 4 261 km closer than the mean perigee distance, but it is still 12 109 km farther than the closest perigee of 21st century.
5 days after its descending node on 14 February 2011 at 08:14 in ♋ Cancer, the Moon is following the southern part of its orbit for the next 7 days, until it will cross the ecliptic from South to North in ascending node on 26 February 2011 at 20:19 in ♐ Sagittarius.
19 days after beginning of current draconic month in ♐ Sagittarius, the Moon is moving from the second to the final part of it.
6 days after previous North standstill on 13 February 2011 at 09:00 in ♊ Gemini, when Moon has reached northern declination of ∠24.080°. Next 6 days the lunar orbit moves southward to face South declination of ∠-23.985° in the next southern standstill on 25 February 2011 at 22:13 in ♐ Sagittarius.
After 13 days on 4 March 2011 at 20:46 in ♓ Pisces, the Moon will be in New Moon geocentric conjunction with the Sun and this alignment forms next Sun-Moon-Earth syzygy.
