           the site tech could not reach the site - current                     
           weather is heavy snow. Consulted with VLBA                           
           Operations Supervisor, recommended that the antenna                  
           be pulled from observing until such time as the                      
           site techs can reach the site and monitor motor                      
           currents in an attempt to dump snow from the dish.
