    Hi Daniel a.o.,
    
    If you look at pictures of the spacecraft, e.g. here:
    
    http://www.jaxa.jp/countdown/h2bf1/pdf/presskit_htv_e.pdf
    
    ....you see the surface of the spacecraft is covered in small solar panels. I 
    suspect these are causing the flares.
    
    It is also visible that the spacecraft is completely covered by orange colored 
    metal foil (thermal blanket), so that is where it gets the distinct orange color 
    from I guess.

    I have observed the spacecraft on two passes now, and on both passes it flared, 
    indeed. So it seems we have a nice light show in the sky the coming days!  :-)
