1431-2234 *HN not observing; 1cm began to warm before the        19667  100  483
           observation started. Site techs investigated,                        
           found blown seal. By the time the 1cm could be                       
           warmed to fix and then cooled, observing would be                    
           over. Decided to warm receiver for work tomorrow                     
           (maintenance day). Pulled site from observing.
