Common Spangle Gall?

Observation - Common Spangle Gall? - Global. Description: The same oak leaf as in a previous observation but this time I'm going for the sputnik-shaped object on the top edge of the leaf. I know the image isn't very clear but I was concentrating on the big gall and didn't notice the smaller ones until later.
