    Paul,
    
    Marco Langbroek already captured this pair flaring in the past:
    
    http://www.satobs.org/seesat/Dec-2010/0076.html
    http://sattrackcam.blogspot.it/2010/11/terra-sar-x-and-tandem-x-flying-in.html
    
    Unfortunately I don't have the old TLE to check their position at that time.
    
    About your observation:
    
    At 8.35.37 UTC the satellites may have exposed a lateral surface (angle 90 
    deg) with
    tilt of 65 deg. I added this surface to the online tracking program so we can 
    check
    if future flares can be predicted (just press on the Predict Flares button):

    By the way, during your observation the angular distance between the 
    satellites 
    was of only 1/15 of degree.
    
    Best regards,
    Simone
