This type of satellite belongs to the ELINT Tselina D group.  After their
operational lifetime most of them begin flashing.  I suspect that failing
gyro's are the cause of their flash behaviour.  Any fuel dump or leak is
very unlikely as they don't have any manoeuvering possibilities.
The last Tselina D was Kosmos 2242 and hasn't been flashing yet.  I think it
will do so in the near future.
