    Obs ML Leiden (Cospar 4353), VISUAL:
    
    28646 05 016A   4353 P 20080201183917060 17 75 1737049+862210 56 S

    * please note remark below regarding 05-016A data
    
    --------------------------------------------------------------------------
    Method: Meade ETX-70 (7cm/F5) @ 14x magnification, stopwatch and Molczan's
    Obsreduce software. Time ref: DCF-77 radio controlled clock
    
    What these numbers mean:

    --------------------------------------------------------------------------
    
    Observations through short clearings in the cloud cover. Completely clouded out 
    during the USA 193 and NOSS 3-4 passes in the morning of the 2nd.
    
    The Lacrosse 5 (05-016A) point is notably off with regard to elset 
    08027.73865531: delta T -1.22s and x-track 0.56 degrees.
    HOWEVER, I cannot rule out I made a mistake in the used reference stars in this 
    case, as the obs was done in a small clearing with clouds running through the 
    FOV almost immediately after the sat passed.
    
    88-078A residuals are fine.
    
    Reference time source is a new DCF-77 clock, as my trusted old one "died" last 
    Wednesday.
