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):

81- 59 A 96-05-29 2:22:38.6 WN 14.9 .5 4 3.7 NOAA 7, F'Ff...fF'F

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.
