           Operator is Betty Ragan.                                             
           Vclock, UT1-UTC, gps delta all check OK.                             
     1721  Begin                                                                
1721-0522 *HN not available due to large amounts of              WEA    100  721
           snow in the dish leading to very high motor                          
           currents.                                                            
1721-0522 *SC Focus brake will not disengage. Site               21989  100  721
           techs are working on it. Antenna is currently                        
           unavailable.                                                         
     1721 %BR rotation is very sluggish, often not quite                        
           getting to the commanded position. It especially                     
           seems to have trouble getting to 335.0; it keeps                     
           stopping at 334.9 and tends to over-shoot if                         
           re-commanded.  There is snow in the dish, including                  
           around the FRM, and probably also ice.                               
     1721 %BR snowing.

1828-1839 *KP autostowed. Probably a power glitch.               COM    100   11
     2046  MK reports scattered cumulus clouds.                                 
     2049 %BR tsys are increasingly high, due to the snow.

     2254  BR is now off by 0.1 again, as it has been.
