    I might have captured something satellite related today in my 
    hydrogen-alpha solar video.  But I am not certain.
    Heavensat lists Cosmos 2251 DEB crossing the solar disk at my location 
    at the correct time 1644:37 UTC but I am wondering if what I have 
    captured is too large to be a chunk of debris?
    I posted an animated .gif here:  3.4 MB  ( Might take a moment to load 
    the eleven image frames.)
    The object is question crosses from screen right to left.
    Any opinions as to whether this might be satellite phenomena welcome.
