    Hi all,
    On one of the images of USA 198 I obtained this evening, there is a second 
    object just south of the satellite. I cannot identify it with any known object.
    The trail length is very short, HEO-like. It is present in one image only, but 
    shows a definite trail in a similar orientation to USA 198, with a flash-like 
    profile. So I think I captured a tumbling object in the bright part of it's 
    tumbling on this image (explaining why it isn't in the other images of the 
    series, taken with 20s intervals). Movement is about 5" / second.
    Positions of "start" and "end" of the trail (assuming movement from S to N 
    similar to USA 198):

    The image (part of it) showing the UNID trail is here:
