Off hand, I can't be very helpful with details, but I have seen geo sats with the naked-eye on several occasions. Once noticed and followed they were later ID'd. First time was around 1984 and it wouldn't surprise me that Russell Eberst ID'd that one for me. I think there is a note in The Astronomer magazine about it in the following month. Most recently, I saw one with the naked-eye last year and could ID it from photographs. At some point, I'll look out the details, but I believe these were in the range of mag +3 to +5.
