Thanks for you answer. I actually should meant a tumbling object. Here is the deal: I work on a high res observation of one of the oldest tumbling rockets in orbit. There are frames taken at the moments of maximum and minimum brightness. I need the right discribtion to annotate on the images, there are no real flashes with this object but just minima and maxima. So I should have discribed it more precisely, my fault...
