Image Eclipse Flyby

Explanation: On June 10 a New Moon passed in front of the Sun. In silhouette only two days after reaching apogee, the most distant point in its elliptical orbit, the Moon's small apparent size helped create an annular solar eclipse. The brief but spectacular annular phase of the eclipse shows a bright solar disk as a ring of fire when viewed along its narrow, northerly shadow track across planet Earth. Cloudy early morning skies along the US east coast held gorgeous views of a partially eclipsed Sun though. Rising together Moon and Sun are captured in a sequence of consecutive frames near maximum eclipse in this digital composite, seen from Quincy Beach south of Boston, Massachusetts. The serendipitous sequence follows the undulating path of a bird in flight joining the Moon in silhouette with the rising Sun.

As Ron noted, the sinusoidal motion of the bird flapping its wings mirrors that of the sum of sines that the earth, sun, and moon all spin in, all aligned in some way for us to see in this image. I mean, at the end of the day, we are all just sums of sine waves.

Maybe a few cosines in there (you know who you are).

<<sine (n.) trigonometric function, 1590s (in Thomas Fale's "Horologiographia, the Art of Dialling"), from Latin sinus "fold in a garment, bend, curve, bosom."

Used mid-12c. by Gherardo of Cremona in Medieval Latin translation of Arabic geometrical text to render Arabic jiba "chord of an arc, sine" (from Sanskrit jya "bowstring"), which he confused with jaib "bundle, bosom, fold in a garment."

I like the picture; mainly of the bird flying across the sky! The silhouette does a nice job of showing the pastern of it''s wings in motion! 8-)

How cheerfully he seems to grin
How neatly spreads his claws,
And welcomes little birdies in
With gently smiling jaws!

Nice work! I also like the 3rd one in the last caption link (The serendipitous sequence).

I wonder if this was a common seagull, or some other bird. It's interesting to look at the smoothness of the overall path (of the center of mass, say). It doesn't vary up and down as much as I would have guessed.

That is a very neat photo! Excellent capture of the bird in motion! The bird reminds me of the phenomenon known as "Rods" that some people believed were UFOs but were most likely insects flying in front of the camera. (https://en.wikipedia.org/wiki/Rod_(optical_phenomenon))
