    I understand that the chances of capturing this one are 
    not good, but it seems worth reporting on it.  Maybe 
    others in Texas or Louisiana watching HST last night saw 
    it as well.  (I'm not sure how far north it would have
    been visible.)
    
    Sunday evening local time (early July 11 UTC), while 
    watching HST, I suddenly noticed to the south of it a 
    bright (magnitude +1.5 and steady), fast-moving eastbound 
    object.  I'm not sure when Mike first saw it, but I think 
    we both clicked at pretty nearly the same time near delta 
    Scorpii (Dschubba, which is at RA 16:00.33, Dec -22.62).  
    I get no match using the big file or the classfd.tle file.  
    My best guesses now for two points (epoch 2000) are:
    
    2:27:48.0  RA 16:00.3, Dec -22.2 (alt 37, az 166)
    2:28:47.0  RA 18:27.4, Dec -24.7 (alt 18, az 134.5)
    
    In looking at charts, it seemed to me to travel fairly 
    parallel to the ecliptic, not very far south of it.
    
    The observing site was BCRC: 30.315N, 97.866W, 280m.
    
    Mike said that it's at least to some extent conceivable 
    that there could be a chance that it might be the same 
    one that I saw nine nights ago, which possibly was a GTO 
    object:
