The Moon, Right Now

Apparent disk of Moon for 2009 Nov 22 at 05:00 UT

Celestial north is up, celestial east is to the left.

This is a synthetic image of the Moon as it would be seen from the Earth at the date and time indicated, the latter expressed in Universal Time (UT). The image is recreated many times per day so that it always represents the current appearance of the Moon. Listed below the image are the lunar longitude and latitude (planetographic coordinates) of the sub-Earth and sub-solar points on the Moon, the phase (the fraction of the area of the apparent disk that appears illuminated), and the angular diameter of the disk in arcseconds.

Description of Lottery Post's Lunar Calendar

A lunar calendar tracks the Moon's phase, or visible portion, over a regular calendar month.

The Moon's phase is tracked from New Moon (when the Moon is completely invisible) to the next New Moon.  That period of time is approximately 29½ days.

Because the average calendar month is approximately 30½ days, the timing of the Moon's phases shifts by an average of about one day for each successive month.

If you compare Lottery Post's Lunar Calendar to other lunar calendars found on the Internet, you may see slight differences.  Lottery Post has made every attempt to use the most precise methods of calculation possible, and in comparison tests, has been shown to be more accurate than most lunar calendars on the web.  However, the fact that the lunar month does not align perfectly with the calendar month means that no lunar calendar in this format is ever perfect.
