    Last night I had my first view of Jason 2 (2008-032A, #33105). I picked it up 
    with my 10x50 binoculars as a reddish mag 5 to mag 6 object at 21:03:07 UTC, 
    21-JUN-08 above Delta Cyg and followed it for two minutes until it reached 
    the Coathanger Cluster (RA 19:25, Decl. 20:11) at 21:05:15. I then swept back 
    in order to see Jason 1 which was about to follow three minutes later but 
    chanced upon a rapidly blinking and flashing object. Some flashes went up to 
    mag 2 or so. As this object seemed to follow the same path as Jason 2 across 
    the sky (it passed the Coathanger Cluster at 21:07:21 UTC) I first thought it 
    to be the booster (although it would have been unsual to trail the  
    satellite). A later check showed that this object must have been SL-12 DEB 
    1992-047M, #28578, on a rather different orbit actually - it was just my 
    location which made it look like the two were on identical orbits for a brief 
    Incidentally, Spacetrack lists the Delta 2 R/B (2008-032B) in a 2161 km x 4362 
    km orbit (epoch 172.90700183) which seems to be totally wrong as this booster 
    was supposed to be deorbited after Jason 2 insertion.
