    Flares: 05-042A flared to mag. -2 at about 21:16:25 UTC
    
    05-042A was -1.25s early.
    
    03-009B was irregular in brightness again. It was 0.4s late. Tracking this 
    object has now become much more interesting, since its orbit is no longer 
    stabilized.
    
    The NOSS 2-1 objects were a surprise catch on the image with USA 186, only a few 
    degrees away from it. Apart from the E and C object the D object is visible in 
    the image as well, but very marginally. It's start more or less overlaps with 
    the end of the E object: so the 2nd point on the latter should be taken with 
    some caution. All trails involved were faint.
    Interestingly, I have the E object exactly on-time, but the C object 3.3s early.
    
    ISS made a nice pass close to Procyon and was only slightly brighter.
