The New Moon for November occurs on Friday, November 5th, which makes the weekend of November 6-7 a fantastic weekend for dark sky observing.
The difference between the “Maine Rule” and the “Astronomical Seasons Rule” is at the point when the season begins and end. The “Maine Rule” assumes the Vernal Equinox as March 20th and then assumes the year is equally divided by a fictitious circular orbit of a mean, average Earth, which fixes the season to begin and end on March 20th, June 21st, September 22nd and December 21st. The “Astronomical Seasons Rule” starts the Seasons on the Equinoxes and Solstices of the year.
Normally these two systems are in sync however on the Winter Solstice of 2010 there is a Full Moon occurring between the midnight that starts the solstice and the actual astronomical solstice (In Pacific Standard Time where I calculate this from – your mileage may vary depending on your timezone.). This moves the “extra Full Moon” from Winter 2011 into Autumn 2010 in the “Astronomical Seasons Rule.” The two systems will be out-of-sync until the Vernal Equinox of 2011.
|Maine Rule Winter Solstice||Midnight (PST)|
|Full Moon||12:14:35 am (PST) (Last full moon of Autumn by the “Astronomical Seasons Rule” or the First full moon of Winter via the “Maine Rule.”)|
|Astronomical Winter Solstice||3:39:35 pm (PST)|
