I agree with this.
The "irregular" second Mm cycle also seems to change as the object traverses
the sky, particularly on a passage with a high azimuth, being better defined
at high Az. angles.
I've not been observing "flashers" long so YMMV.

Subject: Double pattern for Okean-O R/B
Hello everybody!
Okean-O R/B (25861,99039B) seems to have a changing pattern : the
first is a common one (A'A') with a short
period (last record = 0.676 sec on Sept 10) and sometimes a more
sophisticated one (-'MmM-') that is a
constant bright aspect, interrupted alternatively by a very short period
of diappearance and a short period of minimum. Here are my observations
in PPAS format :
99- 39 B 99-07-26 20:52 MJ 52.6 0.1 100 0.526 F'F' after culm
99- 39 B 99-07-26 20:52 MJ 53.8 0.1 100 0.538 F'F' before culm
99- 39 B 99-07-30 21:02 MJ 56.3 0.1 100 0.563 F'F'
99- 39 B 99-08-03 21:15 MJ 56.9 0.1 100 0.569 A'A' before culm
99- 39 B 99-08-03 21:15 MJ 57.5 0.1 100 0.575 A'A' after culm
99- 39 B 99-08-21 21:17 MJ 60.6 0.1 200 0.606 A'A'
99- 39 B 99-08-26 20:17 MJ 249.4 0.1 200 1.247 M-'MmM-'
99- 39 B 99-08-30 20:29 MJ 127.2 0.1 100 1.272 -'MmM-'
99- 39 B 99-09-02 20:13 MJ 63.9 0.1 100 0.639 F'F'
99- 39 B 99-09-06 20:25 MJ 66.3 0.1 100 0.663 F'F'
99- 39 B 99-09-08 19:42 MJ 265.7 0.1 200 1.328 -'MmM-'
99- 39 B 99-09-10 20:35 MJ 67.6 0.1 100 0.676 A'A'
What seems curious is that either one pattern can appear or the other
one, without apparent regularity.
Perhaps somebody has seen this aspect?
