Judging by the size of the image, this must have been either very big or very close to us. I do not think the object you caught on the image is the shadow of something... If it were a shadow, the size of the object creating it must have roughly the same size, that means it would have been hundreds of kilometers in diameter, something that is VERY hard not to pick up earlier.
It may have been meteorological balloon.... They are round like this thing, possibly elongated and the time of the day could be right (in Europe, they are launched around sunset and dawn, and then midnight and noon, I am not sure about here). You caught the silhouette of this on your photo....
Edit: It could have been just an ordiray balloon as well :-)
