    I was watching nasa tv and j-track during the approach,  backflip, and 
    docking.  I remember clearly the view of spain, the basque country, france, 
    and north-central germany.  I wonder if darmstadt was in that view.
    anyhow,  I'm curious,  what equipment or filters were you utilizing to 
    observe the sun during the transit?  did you have  5 scopes?  or were you 
    wearing some special glasses or something?
    I'd sure like to try to see a solar transit of the station sometime.  I saw 
    the venus transit and it was really wicked.
    clear skies!
