Florida Full Moon
A full moon is often thought of as an event of a full night's duration. This is somewhat misleading, as the Moon seen from Earth is continuously becoming larger or smaller (though much too slowly to notice with the
naked eye). Its absolute maximum size occurs at the moment expansion has stopped, and when
graphed, its
tangent slope is zero. For any given location, about half of these absolute maximum full moons will be potentially visible, as the other half occur during the day, when the full moon is below the horizon. Many
almanacs list full moons not just by date, but by their exact time as well, usually in
Coordinated Universal Time (UTC)). Typical monthly
calendars that include phases of the moon may be off by one day if intended for use in a different
time zone.
The date and approximate time of a specific full moon (assuming a circular orbit) can be calculated from the following equation:
where
d is the number of days since 1 January 2000 00:00:00 in the
Terrestrial Time scale used in astronomical
ephemerides; for
Universal Time (UT) add the following approximate correction to
d:
days
where
N is the number of full moons since the first full moon of 2000. The true time of a full moon may differ from this approximation by up to about 14.5 hours as a result of the non-circularity of the moon's orbit.
The age and apparent size of the full moon vary in a cycle of just under 14
synodic months, which has been referred to as a
full moon cycle.
Hi my friends,
I've never thought that math can be that complicated!
I hope you got it.... I don't....*smile*.... The world of Photography is still closer to me than all those mathematical codes and formulas in Astronomy :)
Thanks for all your kind compliments yesterday. I hope all your mothers out there had a fantastic day and you got all spoiled like crazy. I'm still waiting for the phone calls from my kids.... but that's another story!
I've captured this full moon recently and gave him some color too... That's the artist freedom to do what you like with your work, right? Just be creative!
Have a wonderful day!
Susanne
