    In October 1999 I accidentally found Cosmos 2172 flashing when
    it happened to go very close to a flashing Gorizont that I was
    watching:

    I saw it again the next night and reported a flash period of
    146.3 seconds:

    Before too long it drifted onwards to the east and dropped 
    below our horizon.  I'm happy it's been spotted again!
