Once in a Blue Moon

On New Year's Eve, 2009, earthlings experienced an "astronomical phenomenon" - a blue moon.


As dawn approached, I found myself preparing to travel by air from San Antonio, Texas to Portland, Maine.
As I walked to my terminal, this is the sight that welcomed me through the airport windows.

A Blue Moon is the name given to a full moon that occurs twice in one month.  Through the centuries, a Blue Moon has had numerous definitions. According to the Farmer's Almanac, a Blue Moon  is an extra full moon that occurred in a season, each season having 3 full moons.  But a misinterpretation in the 1940's defined it as we now know it.

  Because the monthly calendar was built on the lunar cycle  of 29.5 days, there is usually only one full moon every month. But once every 2-1/2 years, those extra half days add up to two full moons in a month.

The last time a Blue Moon occurred on New Year's Eve was in 1990.  The next time the night sky will host this event will be in 2028, at which time a total lunar eclipse will be visible from some locations in the world.

Nice...I've seen that view quite a bit, though not very much with the moon appearing blue.

This was such an interesting post! So, the blue moon in 2028 better be a cloudless night! LOL

When the moon appears full, we see a reflection of completeness where a reunion of our true nature can be achieved.

WOW! what a great shot! I got up at 3 o'clock this morning and tried to take some photos of the moon shadows being cast by the trees on the snow. No luck - not with my digital camera. Love the full moon, and Mars is making quite an appearance these past few days, too! Thankyou for following my daughter's and my new blog, Karen!
