After noticing this report from Leo Barhorst
"43754 18 097D   4172 G 20190223052746776 F flare
43754 18 097D   4172 G 20190223052756772 F with F-F, P ~ 4 sec."

I observed photographically that object #43754, a Breeze-KM Rocket, to
derive an accurate value of period.

Photos n°8426-72 taken on 24 FEB 2019 18h30.6m to 35.7m UT using a NIKON
D850 + F50mm F/1.8 set at F/4.5, 6 sec ISO 8000.

The rocket was nicely flashing showing bright primary maxima. Secondary
maxima were most often wholly absent. From 29 cycles I got this value:

Rotation period = 10.132s +/- 0.017s.
