           MK starts later @ 1126UT.

     1429  NL AZ#1 low lubrication pressure fault. Called                       
           oncall site tech DJ, he said that it was most                        
           likely due to the cold weather (currently -18C). He                  
           said that he would call Mike (who is doing tape                      
           changes) to check the antenna. Error condition has                   
           gone away.                                                           
     1510  NL Mike called, he will go in later to do a tape                     
           change and check on the AZ lube pressure.                            
     1655  OV wea: partly cloudy, no precipitation, windy                       
     1842  NL site tech Mike called, asking about tape.                         
           Determined that current program needs 3.8 passes                     
           and there are only 2 passes left. He will be on                      
           site in about an hour to mount up new tape.

     1940  FD called oncall site tech Gary to let him know                      
           that they are on the last pass of the tape. He said
