    Hi,
    
    I checked with the TLEs from 10 045 objects and I could not find a match for
    any of the tracks on the image. At the time it was taken, most LEO sats were
    in shadow in that area of the sky. I noticed a faint third parallel track in
    addition to the two we see at the center. This makes me believe these tracks
    are from a plane. If we compare the brightness of these 3 parallel tracks
    with the brightness of the 2 flashes (orange marks), these flashes could
    well have been made by a flashing light on a plane (strobe ?)but not
    necessarily the same. The track creatd by these two flashes is almost in the
    same direction as the 3 parallel tracks.
    
    I've processed your image to enhance the third track. It can be seen here :

    So I doubt these tracks and flashes are from satellites, but I'm not sure.
    Observatory coordinates used for the analysis : 25.51 N  80.59 W  (Are they
    right ?)
    
    Best regards
