Yuri 3A:
90- 77 A 99-09-12 05:00      MM  651.4 0.5   5 130.3  tumb, fl to 9, 10

I watched Yuri 3A from a dark site for a while last night.
It tumbled and/or flashed to 9th, 10th, 11th, or 12th magnitude.
It was usually invisible (fainter than 13th).

The fundamental period seemed to be 130 seconds, but there were many
tumbles/flashes at intermediate times.  There was one flash at 65
seconds.  There were a number of flashes 45 seconds after what I
am calling the "primary" flash.  There were several flashes 45 seconds
before the primary flash.  There were a couple 25 seconds before
the primary flash.

Topex flared to -1 for a few seconds high in the northwest.
