Ron Welch saw it long ago, Kurt Dequick and I saw it two years ago.
I didn't mentioned a magnitude estimate, but it I would have been
bright in the C8, I would have written down it.
According to these observations, the period can be determined 
very well and accurate.  
Because Vince measured a much larger period I guess he saw another
object (maybe a payload ?).

As usual with high objects, the decrease of the period is very,
very slow... , an increase of the period with about 0.1 second
over 12 years, so this one will be flashing for some more
centuries...

According to the Sat Sit Report, the object 69- 69 B = 4069 
is a Atlas Centaur Rocket.  (no solar panels to give specular
flashes ...) 
Some other of these rockets are still flashing nicely 
e.g. 71-  6 B, 81- 18 B, 81-119 B (also rather bright, 
see Leo's reports).

>If any-one has any further candidates I would like to hear of them.
me too, no report yet ?
