    There was a favourable pass of TerraSarX (2007-026A ) and Tandem X (2010-030A) 
    visible for me today at 17:18 UTC, 25-OCT-2010 with the duo directly in the 
    West at an elevation of 43 degrees. At that moment they appeared surprisingly 
    bright (better than mag 2) which was probably due to reflections from one of 
    the slightly inclined lower surfaces (if I interprete drawings I have seen of 
    these satellites correctly). The pair was well seperated in my 10x50 
    binoculars. The leading satellite (TerraSarX according to Spacetrack) was 
    slightly ahead and above the trailing one. 
    I got distracted and briefly looked away but after that I couldn't pick them 
    up anymore. So they might have dimmed at that stage. (But I didn't have the 
    impression that it was a proper flare that I observed). I better put this 
    pair on my standard observation list to check again. It looks pretty.
