Space station photogaphy riddle

What are the bright blotches in Don Pettit's star trail photo's?
In some of these pictures (the last one in the linked series in particular) there are bright white/bluish features on the earth. I understand the star trails and the lines corresponding to terrestrial sources, and will assume there is an ISS part moving in and out of view every once in a while. But those features are more mysterious... There seems to be a repetitive pattern in some of them. Any thoughts/insights?
