          %PT,NL WEA: Intermittant light rain.                                  
          %SC,HN,KP,LA WEA: Recent rains, probable overcast                     
           skies. Gusty winds at SC.                                            
           MK WEA: Gusty winds.                                                 
           Vclock, GPS delta and UT1-UTC time checks all okay.                  
     1113  Begin observation.                                                   
1113-1342 *PT There is a possibility that the data from PT       18879  100  149
           is bad, due to an issue with a data switch on the                    
           formatter board thought to have been fixed yesterday                 
           PCAL plots from the previous observation showed                      
           zero amplitudes.                                                     
1113-1153 *BR FRM Rotation 1st counter-clockwise limit, focus    18878  100   40
           and rotation drive lockout. May have been caused by                  
           high temperatures in the pedestal room, which caused                 
           FRM power supplies to overheat. Site tech was called                 
           out earlier and reset circuit breaker which turned                   
           off the A/C. A/C is now working, power supplies                      
           cooling. Site tech checking on FRM problem.                          
1120-1304 *SC AZ #2 armature/electronics CB fault. Put           18880  100  104
           antenna in STANDBY to see if error clears.                           
     1121 &SC Error will not clear, which means it probably      18880          
           is a real circuit breaker fault. Contacting site                     
           tech.                                                                
     1220  SC WEA: Partly cloudy skies.                                         
     1238 %NL WEA: Site tech reports t-storms in vicinity.                      
     1247  FD WEA: Site tech reports scattered strato-cumulus                   
           clouds, dry.                                                         
     1253  SC Site tech arrives to replace fuses.                               
1302-1306 *KP autostowed, probable power glitch. Repointed.      COM    100    4
     1305 %HN WEA: Site tech reports overcast skies, low                        
           clouds, light rain.                                                  
     1342  End.
