     0144 *Y bad readbacks on track 4, drive #1 - of course                     
           the data is no good anyway due to the head position                  
           problem. Readbacks at other sites all okay.

     0804 *Y operator reports that he has to reboot something                   
           on his end of things, which will affect the                          
           observation, but probably won't be visible from our
