Also egreps of the SeeSat-L archive yield:

old1/206:97:81- 59 A d     NOAA 7: secundary maxima 
old1/287:17:#12553, 81-59A, very nice flasher, two submaxima at +3 or +4, followed

old1/401:50:   81-059A was a flashing satellite on Mar 31. I saw it at magnitude

I'm not sure I understand what you mean when you write 'Ff'F, but I presume 
you mean the same thing I would mean if I wrote F'fF', namely, alternating 
primary and secondary maxima, with the timings made of the primary maxima. 
 
I report here for PPAS(beginning):

The bright, very rapid, untimably rapid, double flashes from NOAA 7 were quite 
striking and, so far as I can remember, unique in my experience.  There were 
also a number of secondary maxima, which may have been irregular in spacing. 
"untimably" may not yet be a word; I use it to mean they were too rapid to be 
timed separately. 
 
Has anyone seen bright, very rapid, double flashes from NOAA 7?  Or other 
objects? 
 
Thanks. 
 
Cheers.

If it isn't win-win, then it's lose-lose.
