Explanation:
Does an alignment like this occur only once in a blue moon?
No, although it was during a
blue moon that this single-shot
image was taken.
During a full
moon that happened to be the second of the month --
the situation that defines a
blue moon --
the photographer created the juxtaposition in late January by quickly moving around
to find just the right spot to get the
background Moon
superposed behind the arc of a
foreground tree.
Unfortunately, in this case, there seemed no other way than getting bogged down in
mud and resting the camera on a barbed-wire fence.
The arc in the oak tree was previously created by hungry cows in
Knight's Ferry,
California,
USA.
Quirky
Moon-tree juxtapositions
like this can be created during any
full moon though, given enough
planning
and time.
Another opportunity will arise this weekend, coincidently during another
blue moon.
Then, the second blue moon in 2018 will occur, meaning that for the second
month this year, two full moons will appear during a single month (moon-th).
Double blue-moon years are
relatively rare, with the last occurring in 1999, and the next in 2037.
