    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...
