           Operators are Jim Ogle and Sonja Mendoza.                            
          %NL and OV did not correctly reposition tapes to                      
           the start of a new pass (previous project was done                   
           at a different data rate.) Don't know if this will                   
           affect it's ability to write data for this project                   
           since both sites will start in the middle of tape                    
           instead of with a fresh pass.                                        
           PT writing on Mk5 disc NRAO-058.                                     
           VCLOCK and gps delta checks okay.                                    
          %High wind gusts at MK; may be some snow in dish.                     
     0129  Begin.                                                               
0129-0130 %OV only had a few hundred feet to reach the end of                   
           a pass so if there are any problems it won't affect                  
           much data. Affected pass was pass #6, tape VLBA0356                  
           on drive #2.                                                         
0129-0149 %NL had almost an entire pass to go so if there are                   
           problems it will affect most of pass #3, tape                        
           SVLB0004, drive #2.                                                  
     0330  End.
