    Report just sent to the MPC.
    I am assuming that the object which is hardly changing in brightness is 
    SYLDA.
    Is this valid, I wonder?

    The ESA Optical Ground Station in Tenerife has taken a series of pictures
    showing these objects. See the article
    
    http://www.esa.int/esaSC/SEM4SJZVNUF_index_0.html
    
    I don't know whether anyone has bothered to process them astrometrically 
    with
    regard to SYLDA and ESC-A.
