Captured Something Strange on ISS Live Feed

    I caught sight of an odd object this morning while viewing the live feed app.
    Everything took place in the small square area between the top solar panel
    of the station and the horizon.
    Photos are from the back facing camera over roughly a 25 min period, 
    (accounting for camera down time and switches of camera etc.).
    Photos should have all id tags attached, date,time,latitudes and so on
    for people who know how to check that stuff out (I’m a bit clueless there).
    
    The first few photos are when I started to see this odd dark shape appear,
    by the 6th photo it is clearly seen on the horizon as a grey ‘blob’ for 
    want of better word…this is when the feed cut out.
    The camera then switched back surprisingly to the same camera.
    
    Then over the course of the next 2 minutes a large grey object (that must
    have depth as it clearly has shadows) proceeded to ‘follow’ the station.
    I got plenty of shots of it before the camera feed cut again.
    They then changed camera for a while, when they came back the sun was
    behind the ISS but this object still seemed tone in the same place it was,
    (Which with my limited knowledge of these things would suggest it was not
    a lens flare.)
    Cut again…
    then the station was nearing its rotation.

I will tidy this up later but at work, and wanted to get it out there fast.
Any comments/ideas much appreciated.
