Using my simple Synodic.rlz program, it is obvious that a period around
24 seconds is possible, if Ed did observe a 'phase shift', i.e. another
surface caused the maxima from 00:55:47 on.

A period of 8.2 seconds looks more probable, since all points are within
+/- 0.4 seconds from the computed average flash peaks, except 00:56:34,
which is 2.0 seconds early.
